Hidden eddy option --b0_flm was utilised to introduce first-order eddy current correction into b=0 volume processing, as a large b-value in conjunction with monopolar diffusion sensitisation has been observed to result in residual eddy current geometric distortions in interspersed b=0 volumes. This however appears to result in failure of execution of the command; multiple different error messages have been observed, but seem to relate to degeneracy of parameter estimation. Removal of this flag has been observed to lead to successful execution in one trial subject; ongoing testing should inform as to whether this flag will need to remain disabled.
