Thanks a lot Ray!
I set radiopt=0 and now I am getting the error message in the output file
as: PB bomb in pb_reslist(): maxnbr too small.
As this is related with the use of the pbsa program, I think the problem in
the calculation using Delphi is with Delphi. Meantime I tried to do the
calculation using just one monomer and I had no problems either using the
pbsa program either using the Delphi program. So, perhaps the problem may be
that Delphi is able to accept only a certain maximum number of atoms…
Could you please give me your opinion about this? Do you have any experience
of using mm_pbsa on large systems? Do you have any other idea about what may
be wrong with the calculation using Delphi?
Any suggestion would be very helpful.
Best regards
Tetrass
