Thanks again for your patient and detailed emails. Yes I do understand that I should sign up for the mailing list and minimize asking you alone, that way others with similar questions would also get to see the solution.
I have a better idea now for most things I plan to do and hopefully not many more complicated tasks. Hopefully I will manage to get my group to use Chimera more often after a demo.

>> Hi Elaine,
>> I will not bother you with too many questions after this last one (at least for a while ;-)). There are a lot of features to explore and I am playing with it and have learnt quite bit today. Also the tutorials on the website are very helpful. I am soon going to be the "Chimera Guy" of our group ;-)
>> But there was one feature I could not figure out. Is it possible to name sections without actually selecting the sequence from the GUI. I need color different parts of large ensembles. Different domains in multiple chains of a single pdb file. For now I open the sequence of one chain at a time form the "Tools > sequence > sequence" and then pick the residues (amino/nucleotide) based on the numbering from the corresponding Fasta file from PDB and then name it from "Select > Name Selection". Is it possible to assign names on a FASTA file?
>> I also looked into the session.py file. I could not relate the numbers corresponding to my names in the session file to the residue numbers or the residues. It would be great if I could assign names in a file and then acess the names to color. Even better would be assign colors to those named selections.
>> Thanks much for your help.
