[Chimera-users] split segmented map

[Elaine Meng]

Dear Gabor,
I don't know of a single step to create separate maps for all the separate segmentation regions, but below is how to do it for one region at a time.

You can use the "mask" command to extract the data within some surface, such as from segmentation. For example, if the original volume data is model #0 and you selected (Ctrl-click in graphics window) the segmentation surface of interest, the command could be something like:

mask #0 sel

... which would create a new volume model.

The mask command has several options, such as for inverting what you get or extracting a slab around the surface, see:

There is also a "segment" command with "exportmask" option to create a map in which the values are the identifiers of the segmentation regions:

I hope this helps,
Elaine
