Dear amber users,
I am trying to generate mol2 file from pdb file of a polymer which is 120 atoms long but I keep bumping into this error message when I try to run antechamber
Warning: the assigned bond types may be wrong, please :
(1) double check the structure (the connectivity) and/or
(2) adjust atom valence penalty parameters in APS.DAT, and/or
(3) increase PSCUTOFF in define.h and recompile bondtype.c
Be cautious, use a large value of PSCUTOFF (>100) will significantly increase the computation time
Error: cannot run "/usr/local/packages/amber/10/intel-11.1-mvapich-1.1/bin/bondtype -j full -i ANTECHAMBER_BOND_TYPE.AC0 -o ANTECHAMBER_BOND_TYPE.AC -f ac" in judgebondtype() of antechamber.c properly, exit
I did get mol2 files from pdb files of polymers which were 118 and 119 atoms long but not for 120 atoms. I googled the error message and came across some suggestions about changing PSCUTOFF values and MAXATOM values in define.h file in antechamber. The cluster I am using has antechamber PSCUTOFF value set to 10 and MAXATOM value set to 256.
Any suggestions ?
Thanks in advance.
