Revision history for Bioperl core modules
Main trunk
1.6 series
The 1.6 series is derived from subversion HEAD and exists as a separate
release branch. This will represent the last of the alternating
developer/stable releases. Code in Subversion HEAD will be divided up into
several smaller packages, including a developer subdistribution for
code considered experimental, unstable, or untested.
Full detail of changes included since the 1.5.2 release are online at:
http://www.bioperl.org/wiki/Change_log. Bugs remaining to be addressed
are online at http://bugzilla.open-bio.org, with specific bugs intended
for this release series highlighted in BUGS.
The following represent the most important changes:
1.6.0 Winter 2009
o Feature/Annotation rollback
- Problematic changes introduced prior to the 1.5 release have been rolled
back. These changes led to subtle bugs involving operator overloading
and interface methods.
- Behavior is very similar to that for BioPerl 1.4, with tag values being
stored generically as simple scalars. Results in a modest speedup.
o Bio::Graphics
- Split into a separate distribution on CPAN, primarily so development
isn't reliant on a complete BioPerl release.
- Bio::Graphics::Pictogram has been renamed to Bio::Draw::Pictogram but
is only available via Subversion (via bioperl-live main trunk)
o Bio::Root::Test
- Common test bed for all BioPerl modules
o Bio::Root::Build
- Common Module::Build-based subclass for all BioPerl modules
o Bio::DB::EUtilities
- Complete refactoring to split up parsing (Bio::Tools::EUtilities),
parameter handling (Bio::Tools::EUtilities::EUtilParameters),
and user agent request posting and retrieval
o Test implementation and reorganization
- Tests have been reorganized into groups based on classes or use
cases.
- Automated test coverage is now online:
http://www.bioperl.org/wiki/Test_Coverage
- After this release, untested modules will be moved into a
separate developer distribution until tests can be derived.
Also, new modules to be added are expected to have a test suite
and adequate test coverage.
1.5.2 Developer release
Full details of changes since 1.5.1 are available online at:
http://www.bioperl.org/wiki/Change_log
The following represents a brief overview of the most important changes.
o Bio::Map
- Overhaul. Brand new system fully allows markers to have multiple
positions on multiple maps, and to have relative positions. Should be
backward compatible.
o Bio::Taxonomy
- This module and all the modules in the Taxonomy directory now
deprecated in favour of Bio::Taxon and Bio::Tree::Tree
o Bio::DB::Taxonomy
- Taxonomy.pm
* get_Taxonomy_Node() eventually to be deprecated, renamed get_taxon().
* New methods ancestor(), each_Descendent() and _handle_internal_id().
* Allows for different database modules to create Bio::Taxon objects
with the same internal id when the same taxon is requested from each.
- flatfile.pm
* get_Children_Taxids() is deprecated, superceded by each_Descendent().
* No longer includes the fake root node 'root'; there are multiple roots
now (10239, 12884, 12908, 29384 and 131567). Consistent with entrez.pm
- entrez.pm
* get_node() has new option -full
* Caches data retrieved from website
o Bio::Species
- Now a Bio::Taxon. Carries out the species name -> specific name munging
that Bio::DB::Taxonomy modules and SeqIO modules used to do, for
backward compatability in species() method.
o Bio::Search and Bio::SearchIO
- Overhaul. The existing system has been sped up via some minor changes
(mostly gain-of-function to the API). Bio::PullParserI is introduced
as a potential eventual replacment for the existing system, though as
yet only a Hmmpfam parser exists written using it.
1.5.1 Developer release
o Major problem with how Annotations were written out with
Bio::Seq is fixed by reverting to old behavior for
Bio::Annotation objects.
o Bio::SeqIO
- genbank.pm
* bug #1871; REFLOOP' parsing loop, I changed the pattern to
expect at l east 9 spaces at the beginning of a line to
indicate line wrapping.
* Treat multi-line SOURCE sections correctly, this defect broke
both common_name() and classification()
* parse swissprot fields in genpept file
* parse WGS genbank records
- embl.pm
* Changed regexp for ID line. The capturing parentheses are
the same, the difference is an optional repeated-not-semi-
colon expression following the captured \S+. This means the
regexp works when the division looks like /PRO;/ or when the
division looks like /ANG ;/ - the latter is from EMBL
repbase
* fix ID line parsing: the molecule string can have spaces in
it. Like: "genomic DNA"
- swiss.pm: bugs #1727, #1734
- entrezgene.pm
* Added parser for entrezgene ASN1 (text format) files.
Uses Bio::ASN1::EntrezGene as a low level parser (get it from CPAN)
o Bio::AlignIO
- maf.pm coordinate problem fixed
o Bio::Taxonomy and Bio::DB::Taxonomy
- Parse NCBI XML now so that nearly all the taxonomy up-and-down
can be done via Web without downloading all the sequence.
o Bio::Tools::Run::RemoteBlast supports more options and complies
to changes to the NCBI interface. It is reccomended that you
retrieve the data in XML instead of plain-text BLAST report to
insure proper parsing and retrieval of all information as NCBI
fully expects to change things in the future.
o Bio::Tree and Bio::TreeIO
- Fixes so that re-rooting a tree works properly
- Writing out nhx format from a newick/nexus file will properly output
bootstrap information. The use must move the internal node labels over
to bootstraps.
for my $node ( grep { ! $_->is_Leaf } $tree->get_nodes ) {
$node->bootstrap($node->id);
$node->id('');
}
- Nexus parsing is much more flexible now, does not care about
LF.
- Cladogram drawing module in Bio::Tree::Draw
- Node height and depth now properly calculated
- fix tree pruning algorithm so that node with 1 child gets merged
o Graphics tweaks. Glyph::xyplot improved. Many other small-medium sized
bugs and improvements were added, see Gbrowse mailing list for most of
these.
o Bio::DB::GFF partially supports GFF3. See information about
gff3_munge flag in scripts/Bio-DB-GFF/bulk_load_gff.pl.
o Better location parsing in Bio::Factory::FTLocationFactory -
this is part of the engine for parsing EMBL/GenBank feature table
locations. Nested join/order-by/complement are allowed now
o Bio::PrimarySeqI->translate now takes named parameters
o Bio::Tools::Phylo::PAML - parsing RST (ancestral sequence
reconstruction) is now supported. Parsing different models and
branch specific parametes are now supported.
o Bio::Factory::FTLocationFactory - parse hierarchical locations
(joins of joins)
o Bio::Matrix::DistanceMatrix returns arrayrefs instead of arrays
for getter/setter functions
o Bio::SearchIO
- blast bug #1739; match scientific notation in score
and possible e+ values
- blast.pm reads more WU-BLAST parameters and parameters, match
a full database pathname,
- Handle NCBI WEB and newer BLAST formats specifically
(Query|Sbjct:) match in alignment blocks can now be (Query|Sbjct).
- psl off-by-one error fixed
- exonerate parsing much improved, CIGAR and VULGAR can be parsed
and HSPs can be constructed from them.
- HSPs query/hit now have a seqdesc field filled out (this was
always available via $hit->description and
$result->query_description
- hmmer.pm can parse -A0 hmmpfam files
- Writer::GbrowseGFF more customizeable.
o Bio::Tools::Hmmpfam
make e-value default score displayed in gff, rather than raw score
allow parse of multiple records
1.5 Developer release
o Bio::Align::DNAStatistics and Bio::Align::ProteinStatistics
provide Jukes-Cantor and Kimura pairwise distance methods,
respectively.
o Bio::AlignIO support for "po" format of POA, and "maf";
Bio::AlignIO::largemultifasta is a new alternative to
Bio::AlignIO::fasta for temporary file-based manipulation of
particularly large multiple sequence alignments.
o Bio::Assembly::Singlet allows orphan, unassembled sequences to
be treated similarly as an assembled contig.
o Bio::CodonUsage provides new rare_codon() and probable_codons()
methods for identifying particular codons that encode a given
amino acid.
o Bio::Coordinate::Utils provides new from_align() method to build
a Bio::Coordinate pair directly from a
Bio::Align::AlignI-conforming object.
o Bio::DB::Biblio::eutils is a class for querying NCBI's Eutils.
Send a Pubmed, Pubmed Central, Entrez, or other query to NCBI's
web service using standard Pubmed query syntax, and retrieve
results as XML.
o Bio::DB::GFF has various sundry bug fixes.
o Bio::FeatureIO is a new SeqIO-style subsystem for
writing/reading genomic features to/from files. I/O classes
exist for BED, GTF (aka GFF v2.5), and GFF v3. Bio::FeatureIO
classes only read/write Bio::SeqFeature::Annotated objects.
Notably, the GFF v3 class requires features to be typed into the
Sequence Ontology.
o Bio::Graph namespace contains new modules for manipulation and
analysis of protein interaction graphs.
o Bio::Graphics has many bug fixes and shiny new glyphs.
o Bio::Index::Hmmer and Bio::Index::Qual provide multiple-file
indexing for HMMER reports and FASTA qual files, respectively.
o Bio::Map::Clone, Bio::Map::Contig, and Bio::Map::FPCMarker are
new objects that can be placed within a Bio::Map::MapI-compliant
genetic/physical map; Bio::Map::Physical provides a new physical
map type; Bio::MapIO::fpc provides finger-printed clone mapping
import.
o Bio::Matrix::PSM provide new support for postion-specific
(scoring) matrices (e.g. profiles, or "possums").
o Bio::Ontology::Ontology and Bio::Ontology::Term objects can now
be instantiated without explicitly using Bio::OntologyIO. This
is possible through changes to Bio::Ontology::OntologyStore to
download ontology files from the web as necessary. Locations of
ontology files are hard-coded into
Bio::Ontology::DocumentRegistry.
o Bio::PopGen includes many new methods and data types for
population genetics analyses.
o New constructor to Bio::Range, unions(). Given a list of
ranges, returns another list of "flattened" ranges --
overlapping ranges are merged into a single range with the
mininum and maximum coordinates of the entire overlapping group.
o Bio::Root::IO now supports -url, in addition to -file and -fh.
The new -url argument allows one to specify the network address
of a file for input. -url currently only works for GET
requests, and thus is read-only.
o Bio::SearchIO::hmmer now returns individual Hit objects for each
domain alignment (thus containing only one HSP); previously
separate alignments would be merged into one hit if the domain
involved in the alignments was the same, but this only worked
when the repeated domain occured without interruption by any
other domain, leading to a confusing mixture of Hit and HSP
objects.
o Bio::Search::Result::ResultI-compliant report objects now
implement the "get_statistics" method to access
Bio::Search::StatisticsI objects that encapsulate any
statistical parameters associated with the search (e.g. Karlin's
lambda for BLAST/FASTA).
o Bio::Seq::LargeLocatableSeq combines the functionality already
found in Bio::Seq::LargeSeq and Bio::LocatableSeq.
o Bio::SeqFeature::Annotated is a replacement for
Bio::SeqFeature::Generic. It breaks compliance with the
Bio::SeqFeatureI interface because the author was sick of
dealing with untyped annotation tags. All
Bio::SeqFeature::Annotated annotations are Bio::AnnotationI
compliant, and accessible through Bio::Annotation::Collection.
o Bio::SeqFeature::Primer implements a Tm() method for primer
melting point predictions.
o Bio::SeqIO now supports AGAVE, BSML (via SAX), CHAOS-XML,
InterProScan-XML, TIGR-XML, and NCBI TinySeq formats.
o Bio::Taxonomy::Node now implements the methods necessary for
Bio::Species interoperability.
o Bio::Tools::CodonTable has new reverse_translate_all() and
make_iupac_string() methods.
o Bio::Tools::dpAlign now provides sequence profile alignments.
o Bio::Tools::GFF now parses GFF version 2.5 (a.k.a. GTF).
o Bio::Tools::Fgenesh, Bio::Tools::tRNAscanSE are new report
parsers.
o Bio::Tools::SiRNA includes two new rulesets (Saigo and Tuschl)
for designing small inhibitory RNA.
o Bio::Tree::DistanceFactory provides NJ and UPGMA tree-building
methods based on a distance matrix.
o Bio::Tree::Statistics provides an assess_bootstrap() method to
calculate bootstrap support values on a guide tree topology,
based on provided bootstrap tree topologies.
o Bio::TreeIO now supports the Pagel (PAG) tree format.

1.2 Branch
1.2.3 Stable release update
o Bug #1475 - Fix and add speedup to spliced_seq for remote location
handling.
o Bug #1477 - Sel --> Sec abbreviation fixed
o Fix bug #1487 where paring in-between locations when
end < start caused the FTLocationFactory logic to fail.
o Fix bug #1489 which was not dealing with keywords as an
arrayref properly (this is fixed on the main trunk because
keywords returns a string and the array is accessible via
get_keywords).
o Bio::Tree::Tree memory leak (bug #1480) fixed
Added a new initialization option -nodelete which
won't try and cleanup the containing nodes if this
is true.
o Bug with parsing labeled nodes with Bio::TreeIO::newick fixed
this was only present on the branch for the 1.2.1 and 1.2.2 series
- Also merged main trunk changes to the branch which make
newick -> nhx round tripping more effective (storing branch length
and bootstrap values in same locate for NodeNHX and Node
implementations.) Fixes to TreeIO parsing for labeled internal
also required small changes to TreeIO::nhx. Improved
tests for this module as well.
o Bio::SearchIO
- Fixed bugs in BLAST parsing which couldn't parse NCBI
gapped blast properly (was losing hit significance values due to
the extra unexpeted column).
- Parsing of blastcl3 (netblast from NCBI) now can handle case of
integer overflow (# of letters in nt seq dbs is > MAX_INT)
although doesn't try to correct it - will get the negative
number for you. Added a test for this as well.
- Fixed HMMER parsing bug which prevented parsing when a hmmpfam report
has no top-level family classification scores but does have scores and
alignments for individual domains.
- Parsing FASTA reports where ungapped percent ID is < 10 and the
regular expression to match the line was missing the possibility of
an extra space. This is rare, which is why we probably did not
catch it before.
- BLAST parsing picks up more of the statistics/parameter fields
at the bottom of reports. Still not fully complete.
- SearchIO::Writer::HTMLResultWriter and TextResultWriter
were fixed to include many improvements and added flexiblity
in outputting the files. Bug #1495 was also fixed in the process.
o Bio::DB::GFF
- Update for GFF3 compatibility.
- Added scripts for importing from UCSC and GenBank.
- Added a 1.2003 version number.
o Bio::Graphics
- Updated tutorial.
- Added a 1.2003 version number.
o SeqIO::swiss Bug #1504 fixed with swiss writing which was not
properly writing keywords out.
o Bio::SeqIO::genbank
- Fixed bug/enhancement #1513 where dates of
the form D-MMM-YYYY were not parsed. Even though this is
invalid format we can handle it - and also cleanup the date
string so it is properly formatted.
- Bug/enhancement #1517 fixed so that SEGMENT line can be parsed
and written with Genbank format. Similarly bug #1515 is fixed to
parse in the ORIGIN text.
o Bio::SeqIO::fasta, a new method called preferred_id_type allows you
to specify the ID type, one of (accession accession.version
display primary). See Bio::SeqIO::preferred_id_type method
documentation for more information.
o Unigene parsing updated to handle file format changes by NCBI
1.2.2 Stable release update
o A series of bug fixes of the Bio::OntologyIO dagflat-related parsers:

of Bio::Ontology::TermI
o brought the OBDA Registry code up to latest specs
o Bio::DB::GenBank
- eutils URL change
- accession number retrieval fixed
o Bio::SearchIO::blast - fix bug #1443 (missing last hits), parse megablast
o Bio::SearchIO::Writer::(HTML|Text)ResultWriter fix bugs #1458,

for translated BLAST/FASTA searches.
o Bio::TreeIO::newick can parse labeled internal nodes
o Bio::Tools::BPbl2seq can properly report strand info for HSPs
for BLASTX if if you provide -report_type => 'BLASTX' when
initializing a BPbl2seq object. Bioperl 1.3 will have better
support for bl2seq in the SearchIO system.
o Bio::Root::IO support a -noclose boolean flag which will not
close a filehandle upon object cleanup - useful when sharing
a filehandle among objects. Additionally code added s.t.
STDOUT/STDIN/STDERR will never be closed by Root::IO cleanup.
o Bio::Tools::Genemark bug #1435 fixed which was missing last prediction
o Bio::SeqIO::genbank

etc).
o Several performance improvements to sequence parsing in Bio::SeqIO.
Attempt to speedup by reducing object creation overhead.
o Bio::DB::GenBank and Bio::DB::GenPept use the NCBI's approved

before 1.2 release.
o Numerous fixes to Bio::SearchIO and sequence parsing (swissprot)
1.1 Developer release
o Bio::Tools::Run has been broken off into a new pkg bioperl-run,
this separation removes some of the complexity in our test suite
and separates the core modules in bioperl from those that need
external programs to run.
o With latest ExtUtils::MakeMaker module installed SGI/IRIX should
not run into trouble running the makefile
o Bio::Location and Bio::SeqIO::FTHelper are fixed to properly
read,create,and write locations for grouped/split locations
(like mRNA features on genomic sequence).
o Bio::Tools::Phlyo added for wrappers for parsing Molphy (protml)
and PAML (codeml,aaml, etc) parsing.
o Bio::Tree:: objects expanded to handle testing monophyly,
paraphyly, least common ancestor, etc.

1.0.2 Bug fix release
o Note: The modules Bio::DB::GenBank and Bio::DB::GenPept provided
in this release will not work after December 2002 when NCBI
shuts off the old Entrez cgi scripts. We have already fixed
on our main development branch and the functionality will be
available in the next stable bioperl release (1.2) slated for
Fall 2002.
o Numerous parsing bugs in Bio::SearchIO::fasta found through
testset by Robin Emig. These were fixed as was the get_aln
method in Bio::Search::HSP::GenericHSP to handle the extra
context sequence that is provided with a FastA alignment.
o Migrating differences between Bio::Search::XX::BlastXX to
Bio::Search::XX::GenericXX objects. This included mechanism
to retrieve whole list of HSPs from Hits and whole list of Hits from
Results in addition to the current next_XX iterator methods that
are available. Added seq_inds() method to GenericHSP which identifies
indexes in the query or hit sequences where conserved,identical,gaps,
or mismatch residues are located (adapted from Steve Chervitz's
implementation in BlastHSP).
o Bio::DB::GFF bugs fixed and are necessary for latest GBrowse release.
Bio::DB::GFF::RelSegment is now Bio::SeqI compliant.
o Bio::Graphics glyph set improved and extended for GBrowse release
o Bio::Tree::Tree get_nodes implementation improvement thanks
to Howard Ross notice performance problem when writing out
unbalanced trees.
o Bio::Location::Fuzzy::new named parameter -loc_type became
-location_type, Bio::Location::Simple::new named parameter
-seqid becamse -seq_id.
o Fixed major Bio::AlignIO::emboss parsing bug on needle output,
was mis-detecting that gaps should be placed at the beginning of
the alignment when the best alignment starts internally in the
sequence.
1.0.1 Bug fix release
o Minor bug fixes to Bio::DB:GFF. Glyph sets improved.
o Parser fixes in SearchIO blast, fasta for more complete WU BLAST
and mixed (3.3 - 3.4) versions of FASTA.
o Small API change to add methods for completeness across
implementations of Bio::Search objects. These new methods
in the interface are implemented by the GenericXX object as well
as the BlastXX objects.
* Bio::Search::Result::ResultI
- hits() method returns list of all Hits (next_hit is an
iterator method)
* Bio::Search::Hit::HitI
- hsps() method returns list of all HSPs (next_hsp is an
iterator method)
o The Bio::SearchIO::Writer classes have been fixed to handle results
created from either psiblast (Search::BlastXX objects) or
blast|fasta|blastxml objects (Search::GenericXX objects). More work
has to be done here to make it work properly and will nee major
API changes.
o Bugs in Bio::Tools::HMMER fixed, including
* #1178 - Root::IO destructor wasn't being called
* #1034 - filter_on_cutoff now behaves properly
o Bio::SeqFeature::Computation initialization args fixed and
tests added.
o Tests are somewhat cleaner, flat.t now properly cleans up after itsself,

Bio::Factory::ApplicationFactoryI
o Dia models for bioperl design are provided in the models/ directory
0.7.2 Bug fix release
o documentation fixes in many modules - SYNOPSIS code verified
to be runnable in many (but not all modules)
o corrected MANIFEST file from 0.7.1 release
o Bug fix in Bio::SeqIO::FTHelper to properly handle
split locations
o Bio::SeqIO::genbank
* Correct parsing and writing of genbank format with protein data
* moltype and molecule separation
o Bio::SeqIO::largefasta fix to avoid inifinite loops
o Bio::SimpleAlign fixed to correctly handle consensus
sequence calculation
o Bio::Tools::HMMER supports hmmer 2.2g
o Bio::Tools::BPlite to support report type specific parsing. Most
major changes are not on the 0.7 branch.
o Bio::Tools::Run::StandAloneBlast exists_blast() fixed and works
with File::Spec
o Bio::Variation::AAChange/RNAChange corrected labels and mutated alleles
in several types of mutations:
1.) AA level: deletion, complex
2.) AA level: complex, inframe
3.) RNA level: silent
o BPbl2seq parsing of empty reports will not die, but will return
a valid, empty, Bio::SeqFeature::SimilarityFeature for
$report->query() and $report->subject() methods. So an easy
way to test if report was empty is to see if
$report->query->seqname is undefined.
0.7.1 Bug fix release
o Better parsing of genbank/EMBL files especially fixing bugs
related to Feature table parsing and locations on remote
sequences. Additionally, species name parsing was better.
o Bio::SeqIO::genbank can parse now NCBI produced genbank database
which include a number of header lines.
o More strict genbank and EMBL format writing (corrected number of
spaces where appropriate).
o Bio::Tools::BPlite can better parse BLASTX reports - see BUGS
for related BPlite BUGS that are unresolved in this release.
o Bio::DB::GenBank, Bio::DB::GenPept have less problems
downloading sequences from NCBI via HTTP. Bio::DB::SwissProt can
use expasy mirrors or EBI dbfetch cgi-script.
o A moderate number of documentation improvements were made as
well to provide a better code synopsis in each module.
0.7 Large number of changes, including refactoring of the
Object system, new parsers, new functionality and
all round better system. Highlights are:
o Refactored root of inheritance: moved to a lightweight Bio::Root::RootI;
Bio::Root::IO for I/O and file/handle capabilities.
o Imported BPlite modules from Ian Korf for BLAST
parsing. This is considered the supported BLAST parser;
Bio::Tools::Blast.pm will eventually phase out due to lack of support.
o Improved Sequence Feature model. Added complete location
modelling (with fuzzy and compound locations). See
Bio::LocationI and the modules under Bio/Location. Added
support in Genbank/EMBL format parsing to completely parse
feature tables for complex locations.
o Moved special support for databanks etc to specialized modules under
Bio/Seq/. One of these supports very large sequences through
a temporary file as a backend.
o Explicit Gene, Transcript and Exon SeqFeature objects, supporting
CDS retrieval and exon shuffling.
o More parsers: Sim4, Genscan, MZEF, ESTScan, BPbl2seq, GFF
o Refactored Bio/DB/GenBank+GenPept. There is now also DB/SwissProt and
DB/GDB (the latter has platform-specific limitations).
o New analysis parser framework for HT sequence annotation (see
Bio::SeqAnalysisParserI and Bio::Factory::SeqAnalysisParserFactory)
o New Alignment IO framework
o New Index modules (Swissprot)
o New modules for running Blast within perl
(Bio::Tools::Run::StandAloneBlast). Added modules for running
Multiple Sequence Alignment tools ClustalW and TCoffee
(Bio::Tools::Run::Alignment).
o New Cookbook-style tutorial (see bptutorial.pl). Improved
documentation across the package.
o Much improved cross platform support. Many known incompatibilities
have been fixed; however, NT and Mac do not work across the entire
setup (see PLATFORMS).
o Many bug fixes, code restructuring, etc. Overall stability and
maintainability benefit a lot.
o A total of 957 automatic tests
0.6.2
There are very few functionality changes but a large
number of software improvements/bug fixes across the package.
o The EMBL/GenBank parsing are improved.
o The Swissprot reading is improved. Swissprot writing
is disabled as it doesn't work at all. This needs to
wait for 0.7 release
o BLAST reports with no hits are correctly parsed.
o Several other bugs of the BLAST parser (regular expressions, ...)
fixed.
o Old syntax calls have been replaced with more modern syntax
o Modules that did not work at all, in particular the Sim4
set have been removed
o Bio::SeqFeature::Generic and Bio::SeqFeature::FeaturePair
have improved compliance with interface specs and documentation
o Mailing list documentation updated throughout the distribution
o Most minor bug fixes have happened.
o The scripts in /examples now work and have the modern syntax
rather than the deprecated syntax
0.6.1 Sun April 2 2000
o Sequences can have Sequence Features attached to them
- The sequence features can be read from or written to
EMBL and GenBank style flat files
o Objects for Annotation, including References (but not
full medline abstracts), Database links and Comments are
provided
o A Species object to represent nodes on a taxonomy tree
is provided
o The ability to parse HMMER and Sim4 output has been added
o The Blast parsing has been improved, with better PSI-BLAST
support and better overall behaviour.
o Flat file indexed databases provide both random access
and sequential access to their component sequences.
o A CodonTable object has been written with all known
CodonTables accessible.
o A number of new lightweight analysis tools have been
added, such as molecular weight determination.
The 0.6 release also has improved software engineering
o The sequence objects have been rewritten, providing more
maintainable and easier to implement objects. These
objects are backwardly compatible with the 0.05.1 objects
o Many objects are defined in terms of interfaces and then
a Perl implementation has been provided. The interfaces
are found in the 'I' files (module names ending in 'I').
This means that it is possible to wrap C/CORBA/SQL access
as true "bioperl" objects, compatible with the rest of
bioperl.
o The SeqIO system has been overhauled to provide better
processing and perl-like automatic interpretation of <>
over arguments.
o Many more tests have been added (a total of 172 automatic
tests are now run before release).
