For years, I have been frustrated by not knowing any way to color
backbones in a structural alignment of two proteins by deviation _*in
Jmol*_.
Jmol's *compare* command aligns two proteins, but I don't know any way
to color one of the backbone alpha carbons by deviation from the other.
Am I missing something?
Swiss-PdbViewer offers multiple methods to do structural alignments, and
after aligning, will color the protein that was moved by deviation from
the static reference structure. However, it offers no way to put the
deviation values in e.g. the temperature column of the PDB file so they
could be used for coloring by Jmol. (It does offer such a function, but
one that works only when the two proteins have identical sequences.)
PyMOL can also align, and color by deviation ("RMSD") with its command
colorByRMSD, but it is unclear to me whether the deviation values can be
saved to a disk PDB file with those values in the B-factor/temperature
column (which could then be used by Jmol). I have submitted a support
request about this to Schrödinger.
If you'd like to see examples of structural alignments colored by
deviation, take a look here: https://pymolwiki.org/index.php/ColorByRMSD
Thanks for any and all help, -Eric
