[chimerax-users] Recreating views

[Tom Goddard]

We don't have mcopy to copy molecule settings in ChimeraX yet -- I agree that would be handy.

A better approach is always save a ChimeraX session used to make the figure, I usually give it the same file name as the figure image file. Then when the model is revised, open the original session, load the new model, color and style it the same as the old, close the old model, and save the revised figure session. It is also useful to use "view name figure" to name the camera view and model positions used for the image so you can rotate the view around and still easily get back to the figure view point with "view figure". The named views are saved in sessions.

With pymol, I saved the get_view matrix in a text file for each view which meant that with one session file I could easily recreate the views if I needed to go back and tweak a figure. In ChimeraX, the closest way that I found to replicate this was to use named views. Am happy to supply a session file if it helps also happy to be educated if there is a better way of doing this, especially as now the ChimeraX session files can get rather large.
