Hi all, I need add a library file for a non-canonical amino acid, but right now I don't have access to quanta. The bonds/angles/impropers I can add by hand but I was wondering if anyone knew of any easy way to generate internal coordinates? Or an alternative route to creating a charm library file.

Cheers and Thanks,

Eli Spencer

I've used it to model a protein of 1200 residues; it just takes longer.

Hello Modeller users,

I was wondering if there was a limit in the amount of residues that MODELLER 6v2 can take. I have been able to model proteins approx 250 in length, but I've not been able to model larger proteins of approx 1300 residues. I would appreciate any suggestions/comments that you may have.

Thank you!
