Hi Ahmad, If you click the “Help” button on Multalign Viewer it will show the help for that tool. Here is the copy of the same information at our website: <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/multalignviewer/fr...> The “Sequence-Structure Association” section in that page explains how to do this. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

I have multiple copies of the same structure open. How to link specific chains of model IDs to Multialign viewer, to be able to highlight sequence of the residues I select? Thanks.
