There are is nothing that simple, as it does all the threshold calculating in the tcl code. You can use:
set gaLinkedVars(fopaqueflag) <1 or 0> SendLinkedVarGroup overlay to turn on and off the opaque flag, and: set gaLinkedVars(fthresh) <float> set gaLinkedVars(fmid) <float> set gaLinkedVars(fslope) <float> SendLinkedVarGroup overlay to change the threshold values. When in 'linear' mode, the tcl code disables the mid and slope fields and calculates fthresh/fmid/fslope from the min and max you enter, and then sends those values back to tksurfer.
