[Chimera-users] ValueError: dimensions too large

I am trying to use the volume eraser, but whenever I click erase, I get a Chimera Error box come up that says: ValueError: dimensions too large. File "C:\Program Files\Chimera\share\VolumeViewer\volume.py", line 1085, in region_grid m = zeros(shape, d.value_type) Does anyone know how to avoid this? I tried shrinking the volume eraser size. I also tried installing Chimera on a different computer to see if that was the problem, but it still isn't working. Thanks, Josh
