[Chimera-users] info pivotting on a single atom

[Elaine Meng]

Dear Christian,
If you use "select" instead of "cofr" does the command select the atom?  I.e., command:

select #3:700.A at N10

If it does not, there is something wrong with your specification.  

If it does, but the cofr command still doesn't work to put the center of rotation there, I have no idea about what could be happening.  Your command seems correct.

You could use menu: Help... Report a Bug, include short description with the cofr command that you tried and also attach your PDB file or a Chimera session file (because we can't fix a bug unless we can reproduce it).  Also include your email address to get feedback about what happens with your bug report. 
Thanks,
Elaine
