Thank you, Dr. Belkin and Dr. Geist.Acutually I mean to select all the ca atoms and calculate their individual rmsf. I don't know the  "measure rmsf" command is proper for the purpose. In my opinion, to calcualte rmsf, we should get an average structure of the trajectory and align each frame to this  average structure and then calculate rmsf of the selected atoms. I don't know if the "measure rmsf" command calculates a an average structure, but obviously it doesn't do the alignment. Could anyone give me a complete script to calculate rmsf?  Thanks.

If you want to run a per-residue analysis, you can do something like: set all [atomselect top all]set residues [lsort -unique [$all get residue]]$all delete foreach residue $residues {    ... your per-residue analysis code goes here ..} On Jun 28, 2014, at 9:45 PM, sunyeping <sunyeping_at_aliyun.com> wrote:Dear all, Could you tell me how to select all residues in a molecule in VMD so that I can operate them one by one?
