Multiple DTI sequences - how to accommodate in BIDS?

24%20PM

My file directory shows 4 DTI different nifti images. What is the best way to name them in the BIDS format? Will this format be correct: sub-rXXsXX_ses-x_dir-LR_dwi.nii.gz?

Hi @asuri

Apologies for missing this. Thank you for your question. Session typically would indicate different scanning times (not during one scanning time). Perhaps acq could work. I would look at the significant difference between the two sets of scans (within one scan appears to be a different dir [LR and RL])

Thanks @franklin, these are 2 phase encodings (up and down or R and L based on sequence). dir-LR and dir-RL seem to be making sense. Thank you very much!
