[gmx-users] RMSD

[Shima Arasteh]

I want to find the structure with the lowest RMSD, so I think it does not make different to set any of pdb files as the ref structure.
I made an attempt and got the RMSD regarding the first pdb file. The RMSD relative to -1 for the ref structure, is written in xvg file. Is my approach logically correct?

Thanks for your suggestions.

 
Sincerely,
Shima

Relative to what?  Each other?  Some universal reference?

That, or g_confrms, depending on what you're actually trying to measure.
