Validation of .bvec/.bval files about bids-validator HOT 6 CLOSED

Looks like something is wrong with google doc URL. It broke lines and only part of it became a link. Copying the whole URL also produces an error that the document doesn't exist.

Sorry:

Thanks. Is the 6 values mentioned above the minimum or the total expected? I'm looking at the .bvec in ds114 and there are 71 values in each row.

Sorry - I was wrong. Here's the corrected text:

Things to check:

• .bvec has as 3 rows
• .bval has one row
• number of columns in .bvec file, number of values (columns) in .bval file and number or volumes in the corresponding _dwi file all have to be the same

from bids-validator.

Ok that makes sense. And is the "number of volumes" defined by the time dimension in _dwi scan header? In the one dataset I have with _dwi scans this value (dim[4) correctly corresponds with the number of bvec/bval values? But I don't have more datasets with _dwi's to check this with.

yes - this is it!
