Dear All,
We're currently trying this year's fsl practical (part Registration and Unwarping). We have problems to preprocess the fieldmap image since the fmap_rads.nii.gz file cannot be generated.
Please see below the error message. Is there something wrong with the installation of the fsl_prepare_fieldmap command or do you have any other ideas what's wrong here?
Any help is highly appreciated!
Many thanks in advance and all the best,
Kristin

Done. Created fmap_rads for use with FEAT.
