Hi @ET_123456,

I have relabeled your post as Software Support and added in the usual support template. Please make posts under this category for future software related questions.

Did you make sure to use a fresh working directory?

Best,
Steven

Hi Steven,

yes, i created a fresh working directory for this as well as fresh derivates directory.

--skip_bids_validation

Please don’t use this. The issue is likely that you have both .nii and .nii.gz files, and this would be caught as an error by the BIDS validator.
