Just increase the MAXRING to 100 times of the default size and recompile
the program. I have no trouble to generate the prep file from a mol2
input file for Buckyball.

All the best

Dear Folks

I wish to work with a large conjugated system, such as Buckyball. On
trying to produce prep file for my molecule by using Antechamber, it
me a message following;

The ring number exceeds MAXRING, increase MAXRING and recompile the
programs, ex
itCannot open file ANTECHAMBER_BOND_TYPE.AC, exit

Would you please provide me a suggestion of which source code and where
should be modified.

Thank you
