[Chimera-users] Need help with fit into segment function

Just select the desired segment with the mouse (Ctrl-click) in the graphics window. If you want more than one segment selected at a time, Shift-Ctrl-click to add to your selection.
In the picture you sent, I only see one surface (not 5 segmentation surfaces) but maybe you just meant to show your whole map. Presumably you used "Segment Map" to produce separate regions before using "Fit to Segment." The 5 segmentation regions with separate surfaces should show up when you used Segment Map.
I'm not sure which tutorial you are viewing, but just now I tried segmenting a map, selecting a segment with Ctrl-click, opening a molecule, and using the "Fit" button without problems. To report problems, use "Help... Report a Bug" in the Chimera menu and include whatever is needed to reproduce the problem, including data or session and description of steps causing the problem. That also sends us information on what type of computer and version of Chimera you are using.
I hope this helps,
