xmmselect (xmmselect-2.67) [xmmsas_20230412_1735-21.0.0]
This area below the “Column selection” area contains two
buttons labeled “1D region” and “2D region”. Pushing either of
them will trigger xmmselect to read spatial region definitions from a
running dsplot or imgdisplay respectively. If this was successful
the region specifications are converted into a corresponding boolean
selection expression which then gets appended to the global expression in
expression entry field.
If no region specification could be read an error dialog box will
be shown indicating the most likely cause of the failure.
