T2w in BIDs format

Dear all,

For each participant I have two T2w (not whole brain): one is T2-weighted TSE sequence and the second is 3D T2-weighted SPACE sequence.

I believe they both should be in the anat folder with t1w, however how should I label them?

best,
Tali

Ahoi hoi @Tali_Weiss,

thank you for posting and welcome to NeuroStars, it’s great to have you here.

The BIDS specification can help you with that, more precisely you can provide an `acquisition` label which allows the distinction between (in your case) sequences. It should be utilized as follows: `_acq-<label>`.
Applied to your data at hand, here’s how it could(!) look like:

``````sub-01/
anat/
sub-01_T1w.nii.gz
sub-01_acq-tse_T2w.nii.gz
sub-01_acq-space_T2w.nii.gz
``````

The exact `<label>` can be freely chosen by you, however, descriptive names are of course preferred. Just make sure that the corresponding `.json` and `.tsv` files have a sufficient amount of information and that your dataset passes the bids-validator.

HTH, cheers, Peer
