This manual page documents briefly the \fBblastclust\fP command.
24
This manual page was written for the Debian GNU/Linux distribution
25
because the original program does not have a manual page.
27
\fBblastclust\fP automatically and systematically clusters protein or
28
DNA sequences based on pairwise matches found using the BLAST
29
algorithm in case of proteins or Mega BLAST algorithm for DNA. In the
30
latter case a single Mega BLAST search is performed for all the
31
sequences combined against a database created from the same
32
sequences. \fBblastclust\fP finds pairs of sequences that have
33
statistically significant matches and clusters them using
34
single-linkage clustering.
36
A summary of options is included below.
42
Complete unfinished clustering
45
Length coverage threshold (default = 0.9)
48
Score coverage threshold (bit score / length if < 3.0, percentage of
49
identities otherwise; default = 1.75)
52
Number of CPU's to use (default = 1)
55
Do not require coverage on both neighbours

66
\fB-i\fP\ \fIfilename\fP
67
FASTA input file (program will format the database and remove files in
68
the end; default = stdin)

Input is nucleotides, not proteins.
