Hi Yangqi, See the Segment Map page <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/segger/segment.html> … under Methodology, four kinds of grouping are listed: • automatic grouping by scale-space filtering (smoothing the data), done by default • interactive grouping by manual selection • interactive grouping by connectivity • interactive grouping using fitted molecules You can follow the links to see more details on each. Maybe by “one by one” you meant using the manual selection method. As far as I know for that method, you would have to select them all, but if they are all in the same area of the screen you could try Ctrl-dragging a selection box rather than clicking one by one. I haven’t tried that, however. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hi Chinera users, I have a density map of a filament. After I segmented the map, I want to group all the outer globular domain (which is part of a monomer) together. Instead of group them one by one, is there a quicker way to do this? I have the helical symmetry of the filaments. Best, Yangqi
