Hi Cassandra,
I don’t know what example you are viewing, but the word “at” is not used; it should be an at symbol @ without spaces before or after it:

match #0 at c5,c4,n7,c8,c9,s10  #1 at c9,c8,n11,c12,c13,s14

There’s a couple examples in the “hydrolases” tutorial. See also the “match” manpage, and general description of command-line atom specification:

<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/match.html>
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/frameatom_spec.html>


I hope this helps,
Elaine
