[PyMOL] displaying solvent mask?

[Peter Adrian Meyer]

Hi pymol users,

Has anyone had any sucess in loading and displaying solvent masks in
pymol?  Checking the list archives and wiki didn't result in anything;
neither did google.  help mask within pymol seems to be talking about
selection stuff.

It seems like the best way would be to modify the ccp4 map
loading/normalizing stuff so that it deals with the mask maptype; but if
there's an easier way I'd greatly appreciate it if someone could let me
know.

Thanks,

Pete

Should anyone else ever need to try this, there turns out to be a very
easy way to do it, assuming that your solvent mask is in ccp4 mask format.

1. use mapmask mskin $MASKFILE mapout $CONVERTED_FILE

2. load $CONVERTED_FILE into pymol, treating it as a normal map. 
Contouring at 1.0 will display the solvent mask correctly.

Of course, it would be better if this had occured to me before spending a
few hours in the depths of layer2/ObjectMask.c ; but that's Mondays for
you.
