Hi all i am using tkmedit in linux 64bit CentOS and i have problems in editing the voxels. My aim is to edit/correct the segmentation of the white matter. I load anatomy and segmented volume with the command:

vglrun tkmedit -f brain.mgz -aux wm.mgz

vglrun is a prefix command that allows my TurboVNC remote session to view the GUI. The problem is that i can add voxels with the middle mouse button but i cannot erase them with right one (it does nothing) Is that a problem occurring to anyone else? Could it be depending from the use of the VNC session?

Best regards Cristiano
