Hi FSL team,
I have fieldmap scans that were acquired to be used to correct DTI data.
For each DTI scan, I have 2 fieldmap scans, acquired with different TE.
I looked at your guide on
http://fsl.fmrib.ox.ac.uk/fsl/fugue/feat_fieldmap.html but I cannot seem
to figure out how to use them...
Each fm scan after dcm --> nii.gz conversion is a 4D niftii which has 4
volumes. The first one is magnitude, it seems. So I need the phase. But
why are they 4 vols? I am attaching a png slice of the 4 volumes of one
of the fieldmap, and hope that someone can shed some light into how
should I use these to correct the DTI scans.
Thank you very much!
