QSIprep Issue - Problem with Reading PhaseEncodingdirection

Hello,

I keep getting the attached error when I run qsiprep. The following entry is the problem. IT should show the j or -j ‘dwi_series_pedir’: ‘’

The problem is with PhaseEncodingdirection. It is correctly set on the json file but it is not reading it correctly.

Hello and welcome to neurostars!

May you please answer the following questions to help us help you:

  1. How are you running QSIPrep and what is your command?
  2. What version of QSIPrep are you using?
  3. Are your data BIDS valid?
  4. Is this error subject-specific or common for every subject
  5. May you print the contents of your DWI json file?

Best,
Steven
