[Chimera-users] Selection command for atoms in different models

Hi Annie,
Sure, you could just select them all with command:

select #0:230,260 #1:232,262

You can also use commands like the following without bothering to select first, e.g.:

color magenta #0:230,260 #1:232,262
color byhet #0:230,260 #1:232,262

Also what I like to do sometimes is just make an alias for a set of residues, e.g. commands:

alias myres #0:230,260 #1:232,262
show myres
color magenta myres
color byhet myres

Command-line atom specification:

alias command:

I hope this helps,
