Hi,

Just wanted to follow up on the issue of just having one fieldmap file for beta-zero correction outlined below.

Thanks for your help,

Afsana

Subject: [Freesurfer] Beta-Zero Correction - No Phase File

Hi,

I'm working with a dataset that outputs only one file (not two separate mag and phase files) for the fieldmap. The data was also collected on non-Siemens scanners: Philips Ingenia and GE SIGNA HDx (not sure if this is the reason the fieldmaps are unpacking differently). I've attached the .dat file for one of the fieldmaps in this email.

If there a way to separate out the mag and phase from the single fieldmap file so I can use epidewarp.fsl?

Thanks,

Afsana
