Hey Everyone,
We have ran into a small problem with antechamber (AMBER8 release).
We are trying to load a pdb that has several rings in the structure (a
tiny nanotube). We run antechamber and the output tells us :
"The ring number exceeds MAXRING, increase MAXRING and recompile the
programs, exitCannot open file ANTECHAMBER_BOND_TYPE.AC"
So, we went into define.h under the $AMBERHOME/src/antechamber and
modified the file to read:
# define MAXCHAR 512 /* hamilton mod from 256 */
# define MAXATOM 1024 /* hamilton mod from 256 */
# define MAXBOND 2048 /* hamilton mod from 512 */
# define MAXRING 4096 /* hamilton mod from 1000 */
After we recompile the program, we get the same error message. We
know for a fact that we do not have more than 4096 rings, in fact we
only have 168 atoms. I looked over the patches and there didn't seem to
be any addressing this concern (bugfix.6 was the closest). If I cut the
structure down, antechamber will eventually run without any problems.
Any ideas?
Cheers,
Karl
