Have you set your sheet and helix part in your pdb? For my personal case,
things you experienced happened when this part wasn't built.
I guess that PyMOL cannot find the secondary structures as softwares like
Rasmol can.
Try to determine your secondary structures with DSSP for example and to
paste
I made a mistake giving the URL in my last post, the correct DSSP page is
now http://www.cmbi.kun.nl/gv/dssp/index.html

Dear Marco,
you can find DSSP at http://www.embl-heidelberg.de/dssp/ or could prefer use
Procheck from the CCP4 series (http://www.ccp4.ac.uk/) and run it on your
pdb file by the "procheck [pdbfile] [chain number] [resolution]" command.
You will obtain 10 postscript files in which you can find draw
