Hi there,
I am trying to use fugue to conduct fieldmap correction. Our data was collected from a Siemons scanner with parallel imaging acquisition. I followed the instruction for SIEMONS data using
fsl_prepare_fieldmap (fsl_prepare_fieldmap <scanner> <phase_image> <magnitude_image> <out_image> <deltaTE (in ms)> [--nocheck]) to make the fmap_rads.nii.gz image.
Then I used fugue to conduct correction on our EPI data using the command as following:
fugue -i epi --dwell=0.00055 --loadfmap=fmap_rads.nii.gz -u outputname
The corrected image is even worse than the original uncorrected image. Is there anything wrong with the fugue command that I used?
