Raji,
Thanks for sending along the map. PyMOL can still read XPLOR
maps just fine -- what's wrong in this situation is that the map doesn't
cover the space of the molecule. To see this:
load buckleddna.pdb
load polya.map, polya, format=xplor
zoom
enable polya
That last command will draw a box around the map, showing you how it
doesn't cover the PDB file. Either you need a model which covers the
map, or a map which covers the model.
Cheers,
Warren
