You might want to rescale your data so that the ratio values are reasonably 
close to 1.

Subject: [HCP-Users] clamping T1/T2 values in CreateMyelinMaps script of post 
freesurfer pipeline

Dear HCP guys,

Why T1/T2 values are clamped between 0 and 100 (while the T1/T2 values are not 
bigger than 10) in CreateMyelinMaps script in post freesurfer pipeline 
(wb-command -volume-math "clamp((T1w / T2w), 0, 100)")?
My dataset has a very different range of values, should I stay with the low and 
high values of 0 and 100 for that command? Or if I change those values, what 
subsequent changes I need to make for the rest?

thanks,
Zahra
