Hi Tosan, Most probably you need a newer version of Chimera.
If you use the Help in the Chimera menu or the help command (for example, "help addaa", the documentation should match what you have. However, if you are going on the web to find the manual, you may be looking at a manual that is "newer" than your version of Chimera.
This addaa feature is included in the list of what has changed after release 1.5.3, <http://plato.cgl.ucsf.edu/chimera/docs/relnotes/snapshot.html#command_changes>
.... so you would need to download a daily build (1.6) of Chimera to use it. <http://plato.cgl.ucsf.edu/chimera/download.html#daily>
I hope this helps, Elaine ---------- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco

Hi, I read in the manual that addaa can be used at the N-terminus. I'm not having any luck doing this. I've been assigning the amino acid to add at the N-term with a lower number, like:
addaa cys,5,alpha :6.a
The error message says 'Can only add to last residue'.
Is there something I may be doing wrong? Thanks, Tosan
