[gmx-users] maximum number of specbonds?

2014-06-19 Thread Soren Wacker
Hi, I am parameterizing an artifical ligand. I use small residue-like fragments and connect them with specbonds in a grid, since I need arbitrary shapes and sizes. Now, I ran into segmentation faults, when the grid becomes to large. Is there an upper limit for the specbonds? How can I fix that

Something is really weird about that system. The error message changes with the number of residues I use. Everything works fine for 2 and 3 residues. With 4 residues I get : ___ Warning: Starting residue DUL1 in chain not identified as
