in displaying a metric on a surface, is it possible to scale it such that the minimum shown is the minimum (assuming all positive) and the maximum value shown (i.e. the upper value in "user scale" if I set it manually in the gui) is the sample deviation, as shown for the column in -metric-information.
the SD is about right as an upper limit for displaying this data (FSL tracking intersections with the surface. but un "distance corrected" since we feel that's a dodgy operation) maybe I can (programatically) make a separate metric in which every column is the SD and use that as a threshold column? or is there an easier way? best, Colin
