you can use the command: set_current_threshold_from_percentile(min, mid,max)
which will compute the thresholds based on the histogram of values On Tue, 3 Mar 2015, Douglas N Greve wrote: > > I'm not sure what you mean. optimal in what sense? > doug > > On 03/03/2015 03:21 PM, Hirsch, Gabriella wrote: >> Hi Fs experts, >> >> I had a quick question about settings thresholds of surface overlays >> in Tksurfer.
