Hi Chimera team,
I’ve made some good headway with the subject of this previous thread (a relatively simple Bio.pairwise2 alignment approach seems to serve to associate chains reasonably well. One further thing I’d like to clarify, is how missing data is stored for a residue attribute in the case of the renderbyattribute functionality?
e.g. if I have the structure sequence, and the scores (just using integers as a simple example for now):
model.residues = MEREYV
Scores = 192984
I can assign those scores reasonable easily as discussed with something to the effect of:
for res, score in zip(model.residues, scores):
setattr(res, “attributeName”, score)
If in the case I have scores with missing data however, what value for missing is acceptable/expected by chimera (“”, None etc)?
E.g:
Scores = 192-84
In which case I envisage doing something like:
for res, score in zip(model.residues, scores):
if score == “-“:
setattr(res, “attributeName, “”) # Or whatever the allowable character/value is?
else:
setattr(res, “attributeName”, score)
Many thanks,
Joe

1. On a related note, is there a need to programmatically ‘refresh’ rangecol/RBA after defining the attribute, as there is with the dialogue box, or should it be happy once the attr is set?
rangecolor will work without any nudging. The Render By Attribute dialog will remain blissfully unaware of the new attributes until you use its refresh menu item. You can use that dialog’s refreshAttrs() method to programatically nudge it. Look at MultAlignViewer/MAViewer.py in your Chimera distribution for an example (search for refreshAttrs).
