[caret-users] Issues using segmentation menu

[Krishna Srihasam]

Hi,

I am trying to segment a brain and I am using the "Caret5 
Tutorial-Segmentation, Flattening, and Registration for V5.5" as my 
guide. I am stuck at manual error correction. I have the left Volume as 
Underlay and the Surefit Segmentation Output is the primary Overlay. 
Then, I do :Menu->Volume ->Segmentation -> Edit voxels -> say turn 
voxels off . After that, when I try to move my cursor ( left mouse 
pressed) over the volume  and nothing happens. There is no change in the 
red colored Overlay. It is as if there  my action to edit voxels did not 
occur at all.  I am using a 64 bit Linux Machine. I tried the same on a 
windows machine and I was able to replicate the same problem. I am using 
Caret 5.6.1. What am I missing here ?? Any help is more than welcome..
