[Chimera-users] Auto-associate define attribute/render by attribute

Hi Joe,
Not sure I understand completely, but did you know that you could include chain in the specification in the attribute file?  E.g. instead of “:3” it could be “:3.A”  for residue 3 in chain A.  It is any command-line specifier, so it could also include the model number.

You would still have to figure out the numbering correspondence to write the attribute files, however.

An alternative approach is to create a custom header file for the sequence or sequence alignment in Multalign Viewer, which would automatically also become an attribute of any associated structures.

I hope this helps,

I currently have the script outputting attribute files as intended, but ideally I’d like to define the same attributes across all the chains of the model, which are made up of a number of different proteins.

Currently the attribute file is only using ‘numbered’ coordinates (:1, :2, :3…etc) , rather than the actual sequence.
