For some reason, the program is not finding in ATOM cards in the "*_lig.pdb.1"
file (or whatever the input pdb file is at this point). You should check
that the pdb file looks OK. You could also add a print statement after
line 562 of the mm_pbsa_calceneent.pm file to see extactly what it is looking
at, to see why the program is never incrementing the $count variable.
