Hi Aldo,
Thanks for the structure! Could you tell me what you did? There was an improvement, but alas I obtained the following errors:
cgaughan.tg-login1:~> antechamber -i ctz_101512_100mod1_mod.pdb -fi pdb -o ctz_101512_100mod1_mod.mol2 -fo mol2 -c bcc -s 2

The sqm.out:

QMMM: System specified with odd number of electrons ( 165)
QMMM: but odd spin ( 1). You most likely have the charge of

Where did the odd electron come from?
Thanks,
Chris

Chris,
Try with the attached file. Let me know if it works.
Best regards,
Aldo

Asunto: Re: [AMBER] Vina Docking model is not accepted in Antechamber
Thanks Aldo,
I did in fact do this (pdb file attached) but to no avail-
error:
Warning: detected more than 10 Residue sequence numbers;
this may be a large multiple residue PDB file;
large multiple residue PDB files are not supported.
Running: /usr/local/packages/AMBER11/bin/bondtype -j full -i ANTECHAMBER_BOND_TYPE.AC0 -o ANTECHAMBER_BOND_TYPE.AC -f ac
For atom[10]:O, the best APS is not zero, bonds involved by this atom are frozen
---Judge bond type for Residue 1 with ID of 11 and Name of CTZ ---
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/AMBER11/bin/bondtype -j full -i ANTECHAMBER_BOND_TYPE.AC0 -o ANTECHAMBER_BOND_TYPE.AC -f ac" in judgebondtype() of antechamber.c properly, exit
basically seems like the same error. Any ideas?
Thanks,
Chris

Chris,
You should try to use the "pdbqt_to_pdb.py" script included in AutodockTools
(/your_installation/MGLTools-1.5.6rc3/MGLToolsPckgs/AutoDockTools/Utilities24/pdbqt_to_pdb.py). If you think something is lost in your pdb, you could send your ligand pdb fileto The PRODRG Server and download the processed pdb file.
Best regards,
Aldo

Asunto: [AMBER] Vina Docking model is not accepted in Antechamber
I docked a ligand to a protein using Autodoc Vina. From the resulting .pdbqt file I extracted the model I was interested in, opened it in PyMol, and saved the structure as a .pdb file (see attached). However, when I try to process this .pdb file in antechamber using :
antechamber -i
ctz_101512_100mod1.pdb -fi pdb -o ctz_101512_100mod1.mol2 -fo mol2 -c bcc -s 2
The following error message is produced:
Warning: detected more than 10 Residue sequence numbers;
this may be a large multiple residue PDB file;
large multiple residue PDB files are not supported.
Continuing, but problems may be encountered.
Running: /usr/local/packages/AMBER11/bin/bondtype -j full -i ANTECHAMBER_BOND_TYPE.AC0 -o ANTECHAMBER_BOND_TYPE.AC -f ac

can anyone point me in the right direction here? Should I not use PyMol to make the pdb file? To convert from PDBQT format to PDB format, the simplest thing to do is to remove the charge (Q) and atom type (T) columns but it seems that PyMol has done this....but maybe lost the proper connect data
Thanks,
Chris
