Dear all, As I want to use the pararestraints program for Xplor-NIH, I wonder which topology file I should use for my protein, which is a protein plus a metal ion (Co2-) linked by S-EDTA. The metal ion is chelated to S-EDTA, and S-EDTA is covalently bonded to Cys by -S-S-. In this case, I don't know which topology file and parameter file (besides protein-1.0.par & protein-1.0.top) I should use. Could anyone help me? Thanks!
Victor
