Dear all,
I am going to get the parameters of AdoMet cofactor in many methyltransferases. But when trying with antechamber, the program halted with the following message:
------------------
[c0225 sam]$ antechamber -i sama.pdb -fi pdb -o sam1.prepin -fo prepi -c bcc -s 2
Running: /home/mjyang/amber9/amber9_mpi/exe/bondtype -i ANTECHAMBER_BOND_TYPE.AC0 -o ANTECHAMBER_BOND_TYPE.AC -f ac -j full
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 MAXVASTATE in define.h and recompile bondtype.C
(4) increase PSCUTOFF in define.h and recompile bondtype.C
Be cautious, use a large value of PSCUTOFF (>10) will significantly increase the computer time
Error: cannot run "/home/mjyang/amber9/amber9_mpi/exe/bondtype -i ANTECHAMBER_BOND_TYPE.AC0 -o ANTECHAMBER_BOND_TYPE.AC -f ac -j full" in judgebondtype() of antechamber.c properly, exit

Could someone please tell me how to fix the problem and what's the intrinsic mechanism of the error?
Any suggestion is greatly appreciated.
Thanks so much for your time.
Have a nice day.
