AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hi, 2086--

So, fat_proc_convert_dcm_dwis is for converting DICOM files to NIFTI. To do the processing step of correcting EPI distortions (along with motion correction and eddy currents), we recommend using the TORTOISE tool, which is also freely available from the NIH:
[science.nichd.nih.gov]

Their preference is typically to have fully matched AP and PA acquisitions, but I believe you can run TORTOISE just using a single phase encode in one set. I will PM you the email addresses of the TORTOISE folks to query about the specifics.
