Another tip: I would also save a position (see "savepos" command) right before you start sectioning. Then you can easily return to that point over and over, with "reset" to the saved position. I often use this general process when I'm developing a command script for movie content.

Dear Smith, I would recommend using "section" yourself manually in the command line with small distance values. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/section.html>

In other words, you could run a script that has all the commands before that point. Then, in the command line keep entering "section" with short distance values.

Although there is a "pause" command that you can put into a script to easily escape or resume execution, it cannot be in the middle of some other command, only before or after it. <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/pause.html>

Dear All,

Wil you please tell me how can I stop or pause the movie playing as a specific point which I want to watch carefully when the section command is in the execution?
