Hi all,

during the segmentation process BRAINS2 not only provides a 
_05_segm.img but moreover a discrete_*.img the latter representating 
a real discrete image with classes for WM (white) and GM (grey). We 
are not sure how this image was created and how to interpret it.

The User's Guide states that it is possible to manually transform a 
segmented image to a discrete image. However, we dont know which 
parameters were used to do this automatically.

Moreover we would like to know if anyone uses the discrete images in 
the manual segmentation process in order to improve the reliability 
or even the validity. Is there a rule of thumb for the paramters 
(class image 2 descrete)?

TIA
