[Loris-dev] Questions and errors uploading BIDS

[Morales Pinzon, Alfredo]

Dear LorisDev team,

I am uploading a BIDS dataset in LORIS. I have the following questions and errors:

1. I added the file sub-<label>[_ses-<label>]_scans.tsv as suggested in the BIDS standard (https://bids-specification.readthedocs.io/en/stable/03-modality-agnostic-files.html#scans-file) to add the acquisition dates, do you take it into account to set the dates in LORIS? If not, how can I set the acquisition dates for the images in the session/visit?

2. I am doing the insertion visit by visit to be able to identify issues instead of running all the subjects at once. In this approach I get an error stating that the participants file (".../data/bids_imports/INFORMS_BIDSVersion_1.4.0/participants.tsv") is different from for every execution. Is there a way I can upload subject by subject without having this issue?

If l have to launch the whole dataset, is the bids script able to check what was already inserted in case there is an error and I have to it again?

3. After insertion of BIDS for a subject in a visit I cannot access the visit in the front end, I am getting a 500 error. Here is the error log in LORIS:
