T2w in BIDs format

1

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
