QSIprep Issue - Problem with Reading PhaseEncodingdirection


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.
