Dear all,
I am trying to use MM_PBSA to decompose interactions in a protein-peptide
complex to residue pairs. For some reason, my calculation aborted
unexpectedly. Probably the sizes of intermediate output files are too large.
But I do have three intermediate files for final calculation:
mysystem_com.all.out(1.5Gb) mysystem_lig.all.out(18Mb) and
mysystem_rec.all.out(1.2Gb).
I am thinking about running script mm_pbsa_statistics.pl to read these three
files and generate final output, but don't know how.
The parameter file (mysystem_statistics.in) for mm_pbsa_statistics.pl is
very simple. There are only three lines:
mysystem_com.all.out 1_120
mysystem_rec.all.out 1_107
mysystem_lig.all.out 108_120
(Am I right about this?)
But trying to run script mm_pbsa_statistics.pl by typing
mm_pbsa_statistics.pl < mysystem_statistics.in
simply didn't work.
What I got is:
USAGE: mm_pbsa_statistics.pl <calc delta ? 0..2> <calc decomp ? 0..2>
<input file> <output file>
[<snap_min> <snap_max>]
Based on this information, I coulnd't figure out how to run
mm_pbsa_statistics.pl correctly.
Could you please help me about this?
Many thanks in advance.
