Hi, everyone,
I have THREE questions about FSL flirt. Would some guy can help me
with this? Thanks.
(1) I found negative values in the results when I use FSL flirt.
Does anyone know why?
My experiments includes the following steps.
First, I use the flirt package to do image coregistration. the
command line is shown as follows.
flirt -in inslice.hdr -ref refslice.hdr -out outslice -omat
omat.txt -2D
Then I used NII package to see the results named outslice.nii,
and found negative values. Why?
(2) How to use flirt to correct distortion induced by eddy current?
(3) Is there any good tools to read and write nii format images?
Thanks a lot.
J.
Best Wishes
