Dear Gromacs,
(Sorry I post this again as I have not got confirmed answer yet)

In the ss.xpm file for secondary structures, can I ask if the first residue shows first, or last residue shows first? I could not find the description 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"?)

I found the original post for the source code at
Can I ask how to use the "repo.or.cz" website? I am not sure how to register it.

I also emailed the author Carsten, but have not got reply.

Thank you.

Yours sincerely
