Hi esin,

I believe I know the workaround. Do you mind sharing some info though:

Can you share the header information from your original nrrd DWI file from pre-QC with DTIPrep with me? And also the header info of the QCed version?

If you are unsure of how to do that, I think I can answer my own question by looking at your DTIPrep QC protocol that you ran on all of the subjects (assuming you kept the same protocol for everyone) and the DTIPrep final QC report.txt file that was output after it finished running for the p1 subject nrrd file that’s giving you problems.

What scanner manufacturer did you collect this data on? Siemens?
