I am also interested in answers to this thread. Can a protein only plot in a protein-peptide complex have increasing backbone RMSD values at 100 ns of simulations? If no, what needs to be done to stabilize trajectory?

The images mean nothing in the absence of your exact commands and evidence of the groups you selected for analysis (copy and paste all this directly from your terminal). -Justin -- ================================================== Justin A.
