[gmx-users] ss.xpm file: first residue showing first, or last residue showing first?

[ZHANG Cheng]

Dear Gromacs,
In the ss.xpm file for secondary structures, can I ask if the first residue shows first, or last residue shows first? Is this already written in the file? 


I also have a chain separator. Can I ask does it show in the beginning or between the two chains?
(Sorry, I asked this question about chain separator before. But if the last residue shows first, it is possible that the chain separator is between the two chains. But I really want to confirm that. Or how can I get contact with the author who wrote the "gmx do_dssp"?)


Thank you.


Yours sincerely
Cheng
