Edges of the topup_fieldcoef image have abnormal signal

[treanus]

Hi,

thanks for making synb0 available.

Recently I have a number of datasets where the edges of the fieldcoef image look strange. The top few rows and the anterior few rows contain wrapped signal. See:

This leads to abnormal signal in the output of eddy. It as as if the signal from the eyes is aliased a few times at the far left of the processed dwi images.

Is this related to the FOV of the T1 and dwi not being equal?
