I realised that my last post was a bit wordy. To summarise:
How can I use nipype to correct for eddy currents and also rotate my bvecs file accordingly, considering that I have not acquired a phase map and only have a single b0 volume?
I would use the all_fmb_pipeline. A zero filled dummy phase map will skip the SDC. The bmap_mag is only needed for registration and masking. The B0 image should do the job.
Thanks, I will give this ago using a dummy filled Phase file. How should I format the epi_param.txt file? I cannot seem to find any documentation for this.
