Dear Dr. Sefa Celik, The “frames” are already “time” — each time step saved is one frame in MD Movie. I do not know if you are viewing the equilibration trajectory output or the production trajectory output, but both of those dialogs say “Time step (fs) = 1” and 5000 steps. However, you have 1001 and not 5000. You did not show the other “Other runtime options” section which includes “Save once every [N] steps” where N is some integer. <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/md/md.html#other> How to convert between time and frames is 1 frame = N (1 fs), but you would have to look in the "Other runtime options" to see what you used for N. Maybe it’s 5. The extra 1 frame is probably just the starting structure. If you mean you want the graph to say “time” instead of “frames,” sorry there is no option to do that. You’d have to use the “Dump Values” button at the bottom of the graph dialog to save the values to a text file and then use some other program to make a graph with the labels etc. that you want. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Dear Dr.
I am using Chimera software(windows platform). I tried to get rmsd graph(using the plotting in the MD Movie trajectory viewer). And I got the result. But, graph's x-axis "frame" and y-axis "rmsd" value. I want the x axis to be the "time". Briefly, I want to see how the value of rmsd changes with time. I added files to the e-mail. Can you explain what "1001 frames" mean? And how do I convert "1001 frames" to time. I want to see the RMSD change by time. Can you help with this? Could you explain in detail?
