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 c

no problem. The space bar is bound to the "apply" button, which should do the trick for you On Mon, 6 Apr 2009, Lloyd Elliott wrote: 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 o

This looks like a problem we had with an older version. What version of freesurfer are you running? Martin Kavec wrote: Hi, I am trying to mask a non-brain tissue left by watershed based on the cortical surfaces. I found that all what I need to be left is in aparc+aseg.mgz, so I converted it

Hi Dough, this data were analyzed using 4.0.4. So indeed it not the latest, which I am running normally. From which version has this been fixed, so I can check, before re-runing. From which point should I rerun the analysis. Thanks, Martin On Monday 06 April 2009 18:42:36 Douglas N Greve wrot

I thought it was 4.0.3, so maybe that's not it. Can you look at the ribbon.mgz file? You can load it as a segmentation, ie, tkmedit subject orig.mgz -seg ribbon.mgz aparc+aseg is suppossed to inherit the cortex from ribbon.mgz doug On Mon, 6 Apr 2009, Martin Kavec wrote: Hi Dough, this

but you are using aparc+aseg to generate the mask, so if aparc+aseg is perfect, the mask should be as well. Do the mask and aparc+aseg match? On Mon, 6 Apr 2009, Martin Kavec wrote: Doug, ribbon (aparc+aseg) looks perfect, and corresponds to the surfaces ?h.white. Thanks, Martin On Monda
