Hi,
I am trying to run antechamber to get parameters for the modified residues found in TRNA (6tna.pdb). Listed below are the commands I gave and the corresponding error message. I seem to get output files, but because of this error message I am not sure if they are correct and if I should be doing something else. Second, if I get the parameters for the modified residues can I use them for other structures if the modified residue has the same atoms (basically a slightly modified version of the 6tna.pdb structure)?
Thanks for the help

Cannot successfully assign bond type for this molecule, 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
