I was actually thinking about a related approach. Could one include a feature in PyMOL allowing the user to save notes with a session? I've really come to like saving sessions but going back to them later I often wonder what the objects are exactly, what the views were meant to represent, which views are saved, which color scheme I used. Briefly, details that help recreate scenes or images.
I've sent emails not too long ago arguing that one should simply write scripts, and all will be obvious. I stand corrected (thanks, Warren) because it won't. If you're pdb file is gone, your script will only take you on a long search through the dark corners of all available hard disks but not to brilliant figures.
Gilleain, I'm not sure you would want to save a session with every png because that would inflate the size of your image significantly. But it'd sure be cool to have a snapshot saved in the session file to have a thumbnail to look at.
I just had an idea for a plugin, but I know I won't have time to make
it, sooooo...I thought I would mention it in the hope someone else
Basically, I often make snapshot images (pngs) of scenes. The problem
with doing this is that I have learned to be careful to make the
filename tell me what it is. For example : nacatgrip_1fmn_201_203.png.
Otherwise, I look at the picture 6 months later and wonder what it
This would be a lot easier if there was a snapshot plugin that could
store an image and metadata about the image - the path to the
structure file, structure names, comments, etc.
In fact, a truly clever thing would be to store the session along with
the image, and you could browse sessions by looking at thumbnail
Anyway, just a thought.
