  The VMD atom selection language has keywords "index" and "serial" for
0-based or 1-based atom selection by their sequential ordering. The selection
keywords for things like residues make use of information commonly found
in the PDB, so you have residue names or residue indices, fragment indices,
etc. I don't know the syntax of the selection language in MDAnalysis so
you'll have to answer that question for yourself, or ask other mailing
list contributors.

Best regards,
