Dear sir

I am trying to calculate per residue rmsd. The protein i am using has 3
residues with negative indexes. so when i execute "rmsd_residue_over_time
top $sel_resid" i am getting following error: atomselect: cannot parse
selection text: protein and resid -3 and noh

i have 3 segment in the pdb file. Please let me know how to deal with the
issues. Also, i wanted to know how to merge trajectories from previous run
for RMSD or energy analysis (trajectories generated during different time
interval).

Regards
