One more suggestion about how to convert frame numbers to seconds in the perframe command for showing a label. You can use the perframe "range" option with floating point values, for example, perframe "echo $1" range 0,0.4 frames 11 0 0.04 0.08 0.12 0.16 0.2 0.24 0.28 0.32 0.36 0.4 So you would use the range option to specify the time interval corresponding to the specified number of frames (minus one). tom

Dear chimera users,
I have two doubts regarding per-frame actions:
1) I am trying to add a counter in my script (commands script, no python script).
It works when I do it as a per-frame action in the MD Movie window (just as Elaine does in the’Trajectory and ensemble Analysis Tutorial’) but I am not able to do insert it in my command script:
Something like this:
movie record 2dlabels create timer text “frame 0" size 40 color white alias ^actions 2dlabels change timer text "frame <FRAME>"
perframe actions; coordset #0 1,216000,1000 load false; wait 216; ~perframe movie encode movie.mp4
2) What I really want is to show nanoseconds, not frames. In my case 1000 frames = 1 ns. When I write frame <FRAME>/1000 in MD Movie window, obviously, it does not work. Any suggestion to make it work and insert it in the commands script?
Thank you very much!, Clara
