Qsiprep requiring a pe_direction of either i or j for macaque data

Hey all,

I am trying to analyze macaque data using qsi-prep. In a previous thread, someone had recommended that this is possible with the option “–dwi-only” and “–infant”. However, I get an error with the following message :

traits.trait_errors.TraitError: The 'pe_direction' trait of a DiffusionSummaryInputSpec instance must be None or 'i' or 'i-' or 'j' or 'j-', but a value of 'k-' <class 'str'> was specified.

I would ideally prefer to not modify the header or change the orientation as there are a large number of files. Is there no support for running qsiprep with the k/k- directions?

Thanks advance,
