Hi, so when I uploaded my dataset in the bids-validator, I got the above error, with more details as “We were unable to parse header data from this NIfTI file. Please ensure it is not corrupted or mislabeled”.
The nifti file is saved as this “HCP_DATA/sub-103818/dwi/sub-103818_acq-multishell_dwi.nii.gz”
However, when I ran this using the command line version, it didn’t show me this error.
Also, there was a dataset which has been made BIDS-compatible by my senior and I had replicated the same structure. However for her case, it didn’t show this error either in the web-version or the command line version. Is there any error in my data?
It seems to be a bug or an over-interpretation of the new release of BIDS validator, I got the same error on my data even though the nifty files are perfectly readable by FSL for instance. I moved on to try with an earlier version of the BIDS validator (v1.9.3) and didn’t get this error.
