Execute wheel command: draw helical wheel for the sequence which
9
is kept in the sequence buffer.
12
(1) Pointer to MolComplexS structure.
13
(2) The number of macromolecular complexes.
14
(3) Pointer to RuntimeS structure.
15
(4) Pointer to ConfigS structure.
16
(5) Pointer to GUIS structure.
17
(6) Pointer to NearestAtomS structure.
18
(7) The number of pixels in the main window free area.
19
(8) Pointer to refreshI.
20
(9) Pointer to the remainder of the command string. This command
21
may be given without any keyword, with keyword OFF or with two
22
residue serial numbers.
25
(1) The main window mode changed to 2 (default is zero), i.e. the
26
main window will be switched to helical wheel plot.
30
(1) Positive (command) code on success.
31
(2) Negative (error) code on failure.
34
(1) This command reinitializes the NearestAtomS array, except if
35
the additional keyword is not recognized.
37
(2) Helical wheel is drawn for the sequence which is currently in
38
the sequence buffer. This sequence will be typically short.
