Structure Viewers
Program Website Comments
Chimera http://www.cgl.ucsf.edu/chimera/ Alignment viewer for structural analysis; molecular dynamics; electrostatics viewing
PyMol http://pymol.sourceforge.net/ High quality molecular graphics; electrostatics viewing; movie generation; scripts
VMD http://www.ks.uiuc.edu/Research/vmd/ Easy to use; quality graphics; handles many file types; movie generation; scripts
SwissPDB http://www.expasy.org/spdbv/ Easy to use; modeling; mutations, H-bonds, angles and distances between atoms
Cn3D http://www.ncbi.nlm.nih.gov/Structure/CN3D/cn3d.html Basic viewer; simultaneously display of structure, sequence & alignments
RasMol http://www.openrasmol.org/ Basic viewer; widely used; many severs return RasMol scripts for viewing of results
1) These viewers must be installed locally. The software is supported by Windows, Mac OS X (may require X11 window system) and UNIX.
