hello sr,in response to ur suggestion,
when i gave the following command:
antechamber -i plp.pdb -fi pdb -o plp.mol2 -fo mol2 -c bcc -s 2
i got the following error:
Running: $AMBERHOME/exe/bondtype -i ANTECHAMBER_BOND_TYPE.AC0 -o
ANTECHAMBER_BOND_TYPE.AC -f ac -j full
Warning: the assigned bond types may be wrong, please :
(1) double check the structure (the connectivity) and/or
(2) adjust atom valence penalty parameters in APS.DAT, and/or
(3) increase MAXVASTATE in define.h and recompile bondtype.C
(4) increase PSCUTOFF in define.h and recompile bondtype.C
Be cautious, use a large value of PSCUTOFF (>10) will significantly increase
the computer time
Error: cannot run "$AMBERHOME/exe/bondtype -i ANTECHAMBER_BOND_TYPE.AC0 -o
ANTECHAMBER_BOND_TYPE.AC -f ac -j full" in judgebondtype() of antechamber.c
properly, exit
and i got the following files only:
ANTECHAMBER_BOND_TYPE.AC ATOMTYPE.INF ANTECHAMBER_BOND_TYPE.AC0
and all are intermediate files. it seems as if the run wasn't finished properly
to get output file.
i did this without reducinh the molecule. as i was trying to reduce the molecule
by following command:
reduce plp.pdb > plp_new.pdb
i got the following error:
-bash: reduce: command not found
then i tried to add hyrogens using pymol and got the file and tried to give
antechamber command as above, still the same error came.moreover i cudn't
understand the errors also.
plz help me out to extract the parameters for pyridoxal phosphate molecule.
thanx in advance
monica
