[chimerax-users] Surface rendered trajectory

[Elaine Meng]

Eric's answer is great -- I would only add the minor point that after using the "2dlabels" command to create the label, you could use the "move label" mouse mode to drag it to where you want it in the window.

In the Right Mouse tab of the ChimeraX toolbar, the icon for this mousemode looks like "ATP" with an arrow under it.  Click the icon to assign the "move label" function to the right mouse button (= trackpad + Alt on Windows, trackpad + command key on Mac).
  
2dlabel command:

I hope this helps,

Second, the two occurrences of "23" should be changed to however many frames your trajectory actually has.  Third, in case sending this by mail munged the quote characters, the outside quotes around the coordset and 2dlabel command are double quotes, and the inside quotes around Frame $1 are single quotes.  Lastly, the "$1" occurrences will be replaced with the frame number as the perframe command executes, which is why the 2D label will show the correct frame number as the trajectory plays.  You could of course change "Frame $1" to some other phrasing as you prefer.
