A recipe for reading surfaces from Roman Laskowski's SURFNET program (for finding cavities in macromolecules) into PyMol for visualisation.
1. Create your surfaces in "CCP4" format in SURFNET.
Aside: SURFNET can be compiled against ccp4 version 5 and 6 libraries by following the instructions in the SURFNET distribution and modifiying the link lines at the end of ccp4link.scr to replace
$CLIB/libccp4.a
with
$CLIB/libccp4f.a $CLIB/libccp4c.a
2. Use Gerard Kleywegt's mapman from the USF RAVE package to convert the CCP4 density map to XPLOR format
e.g. in a shell on LINUX:
$ lx_mapman
MAPMAN > READ map1 gaps.den
MAPMAN > WRITE map1 gaps.xplor XPLOR
3. Open the XPLOR map in PyMol
4. Generate a mesh or surface object from the map using isomesh or isosurface.
e.g. on the PyMol command line
isomesh gaps_mesh gaps 100.0
