Subject: RESP for deprotonated tyrosine and lysine

Dear Prof.David Case

I want to do the deprotonated tyrosine and lysine (basic form) calculated
using Antechamber with
the RESP charge method based on HF/6-31G* calculations conducted
with Gaussian 98. I have done the guideline that you give in AMBER Archive
(2002) ---
Subject: *Re: RESP tutorial *But I already do for lysine by all steps belows

antechamber -i lys.pdb -fi pdb -o lys.gcrt -fo gcrt
g03 <lys.gcrt>tyr_g03.out &
antechamber -i lys_g03.out -fi gout -o g03_lys.prepi -fo prepi -c resp -s 2

and the results were shown belows;

Running: /AMBER/amber9/exe/bondtype -i ANTECHAMBER_BOND_TYPE.AC0 -o

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 "/AMBER/amber9/exe/bondtype -i ANTECHAMBER_BOND_TYPE.AC0
-o ANTECHAMBER_BOND_TYPE.AC -f ac -j full" in judgebondtype() of
antechamber.c properly, exit

what did I do wrong? I don't know but ,may be, come from the structure I
build or any reasons.

So, please tell me how to do that ,by the way, this attached file should be
useful for you

,Thank you
