I'm trying to perform for the first time volumetric measurements for
white/grey matter and CSF on a subject with Parkinson disease using fsl
and I would appreciate again your help.
We have aquired T1 images (256X256X124) and I understand that I have to
# run BET
# remove the bias field
# set the number of input channels =1
#set the number of classes= 3 (for white.gray matter and CSF)
# use a priory probability maps for initialization (Talairach template),
because at the end I would like to compare Parkinson group / Control Group
My questions are:
1. I would like to do segmentation only for primary auditory cortex so I
wonder is it a way to specify ROI mask?
2. After the segmentation is done should I use SIENNA software to find
the volume for white/gray matter?
