[PyMOL] saving maps for a presentation

[Tatyana S. <tat...@gm...>]

Dear Pymol experts!

I am going to make a presentation with running Pymol during it. I would like
to show small details (ligand densities) of several ED maps in this
presentation.
I will have to keep several Pymol instances running due to setup of the
presentation to avoid loading big files on the fly.
I am worrying that if I open and carve all maps within one of the Pymol
instances it will be very resource consuming. That is why I am wondering if
there is a way to save the carved ED around the ligands as  a volume object
and use this for the life presentation instead of the maps?  I found a short
article named "volume" and mentioning of the "map_new" but I could not fine
a fuller description of these commands.

The main problem is that I am using stereo projection and do not want to
render pictures and movies, therefore all view will show up in 3D.

I am using Win7 system with the Pymol v1.3. If there is any additional
information or details are needed - I am more than happy to provide them!

Thank you very much in advance!

Cheers,
Tanya
