Hi all,
We are running Eddy on a large number of our DWI scans, which have already been collected. They do not have the opposite phase encoding required to run topup as-is, but we have collected fieldmap images. It appears that topup estimates the fieldmap/bias, and then applies some processing on that estimation, which can be passed on to Eddy. I was wondering if instead of estimating the fieldmap, whether we could use our own collected fieldmaps, with some additional processing? Is there a better alternative, given our acquisition?
Note, this might be a duplicate of this, but I didn't see any responses:
