Hi Lily
Maybe this question should be put on namd mailing-list ;-)
Usually this kind of error appears when the starting coordinates have atom clashes, confering to those atoms a big VDW repulsion energy.
But you say that the coordinates came from a previous md run. Are you sure you're giving to namd the correct velocities/coordinate files?
Try to do a EM on the coordinates that you're feeding to namd, and check if that error appears again.
Regards,
Nuno

Subject: vmd-l: restart simulation with NAMD
``atoms moving too fast; simulation has become unstable''
I am fine with a start-from-scratch run. But as I resume the simulation with restart conformation files, I got the error messege as above. Is there a problem with my original PDB or PSF file? Or there is something wrong with my previous simulation (There is no error message)?
I changed the cutoff value and pairelistdist value, the problem is still there.
Do you have any advice?Thanks!
Lily
