session ignore

[juansanchezpena]

What would you like to see added in fMRIPrep?

Can there be an ignore session arg?
I am working with large datasets and many different protocols and using 25.2.1. I will also be using xcp after these data are all processed.
Can you help to clarify the best approach for these two case scenarios?

Case 1: Sequential Sessions with Shared Anatomy

You have five sessions of data collected one week apart, with a single anatomical scan acquired during the first session. Your goal is to process each session while using the anatomy from the first session for the subsequent sessions. You want to avoid reprocessing any sessions that have already been completed.

Steps:

1. Session 1 (ses-01): Process this session normally, including the anatomical data.
2. Session 2 (ses-02): Process this session using the anatomical data from ses-01.
3. Session 3 (ses-03): Process this session using the anatomical data from ses-01.
4. Session 4 (ses-04): Process this session using the anatomical data from ses-01.
5. Session 5 (ses-05): Process this session using the anatomical data from ses-01.

Case 2: Multiple Sessions with Shared Anatomy

In this case, you have two sessions (ses-01 and ses-02), each with their own anatomical scans. You process these sessions using the --subject-anatomical-reference sessionwise option. Now, you are acquiring a third session (ses-03) that has some missing BOLD data from ses-02, but you want to use the anatomical data from ses-02 for this new session.

Steps:

1. Session 1 (ses-01): Process with its own anatomical data.
2. Session 2 (ses-02): Process with its own anatomical data.
3. Session 3 (ses-03): Process this session using the anatomical data from ses-02, despite having missing BOLD data from ses-02.

Do you have any interest in helping implement the feature?

Yes
