How to rotate crystal/molecules 3D ?

[patrick295767]

Hello,

I am looking for a wait to check in 3D a molecule of a crystal, and would be looking for a such 3D viewer than could rotate them:

What would be the best suited prog?

The best crystal structure viewer I know is PyMOL (it's in the repos, just open up synaptic and search for it).
It's really good for looking at protein and nucleic acid structures, and it works for simpler molecules too.
Not sure about structures of salt crystals, but I don't see why that wouldn't work too if the structure file is in a format PyMOL can read (PDB, XYZ, CIF, MDL Molfile, ChemDraw, CCP4 maps, XPLOR maps and Gaussian cube maps).
If you need help getting started go to pymolwiki.org.
