Hi there chaps.. I'm adding a half a dozen NAG residues to O linked Threonines in my protein. As the standard NAG.py script seemed to crumple the sugar during the minimization - I've started from scratch and gone back to old xplor to generate my PSFs.
Things are going ok but I was wondering about syntax. in the defining angles (and in impropers) in the NAG to ASN residue ADD ANGLe +ND2 -C1 -C2 could someone tell me what the + and the - are for? It is a simple question and there may be more to follow.. thanks James James Swarbrick Monash University. Oz
