Hi,
I have two diffusion datasets collected from the same subject back to back
and I would like to average the two datasets to decrease the noise.
I use FLIRT to register one scan to the other and then fslmaths to add the
two data sets (fslmaths data_a -add data_b data_sum) and then divide by 2
(fslmaths data_sum -div 2 data_average). Then I fit the tensors and I am
having trouble viewing the FA map overlaid with V1. When I modulate V1 to FA
the image disappears. I have tried to use different max/min display
intensities for FA, but none of them work. Do you have any suggestions?
Sincerely,
Anastasia
