Hi Carsten & Shane, I assume Carsten is looking for cmd.get_raw_alignment(). Recent versions of PyMOL can create an alignment object with all alignment commands (align, super, cealign). get_raw_alignment returns the (model, index) keys for all pairs. http://pymolwiki.org/index.php/get_raw_align

Hi Carsten, This sounds like a non-trivial problem, my understanding is that it's still an ongoing challenge to best align dissimilar structures. Other ways of aligning structures involves using the vectors from secondary structure elements, or feeding in (multiple) sequence alignments. All have t

Hi, How can I best determine the distance between matching pairs of atoms in two or more aligned structures? Fairly easy to do when the two aligned structures are the same, but how does one go about when the structures are not the same? The problem is that I cannot figure out how to dependably
