The problem is that the Apply Close and Help button controls don't appear on the mac because the window is too long (MacBook laptops have a maximum resolution of 1280x800) (I didn't realise there was such a button because the beveling behind the rest of the controls makes it look like the window ends before the apply ---). I actually thought that this might be the case after I first posted, so I searched mac forums for a way to move windows without having to drag the title bar but I could only find other people with the same problem. I suppose I will hack the tcl to make it display in columns or add a scrollbar or something.
Rather embarrassed, L

did you try clickin "apply"? On Mon, 6 Apr 2009, Lloyd Elliott wrote:
Yes, I did try right clicking to set the upper threshold. When I left click, or right click, the respective bar moves, but the colour map remains unchanged. When I click "copy settings to layer" the bars almost always reset. I've managed to make them not reset at least once, but the colour map still remained unchanged and I've been unable to reliably reproduce this non-resetting behaviour.
Thanks! L

Hi, I am trying to modify the colour map of an overlay in tksurfer. Unfortunately, the changes I make to the View -> Configure -> Overlay tcl/tk control are either ignored, or end in errors. For example, if I left click on the histogram to set the lower thresh hold, and then click 'coppy settings to layer', then the thresh hold resets to the original value. If I change the X Axis Range manually, for example by entering '6' in the Max edit box, then I get something like this error whenever I try to change something: ERROR updating histo: impossible limits (min 6.73089 >= max 6.73089) for axis "x" I'm guessing that this is a bug --- that is, it's not that I am misusing these controls. I just want the brain to be coloured according to the whole range of values in my w file --- ie, for the heat map, the minimum should be the darkest blue and the maximum should be the brightest red (no gray where I guess freesurfer assumes p>whatever --- this overlay is not a statistical test).
