Missing physiological data #282

@HDhanis

Description

@HDhanis

Hi there,

This is not exactly a technical question but I thought I would give it a go anyway.

I have been using the PhysIO for a while now in multiple fMRI projects, however, now I am going to start working with a delicate patient population for which quite some data is already acquired. Unfortunately, due to complications with having these patients in the scanner, physiological data is missing for around 10% of them.

The main question is : Have you encountered this, and do you have any advice on how to deal with it?

Some thoughts: I am reticent about changing the entire preprocessing pipeline to do denoising with ICA versus retroicor, however ICA would be doable in all patients including the ones with missing data. Would it be acceptable to do ICA based correction in the participants that don't have physio, and then include a covariate in the follow-up analyses that differentiates the strategies?

Really a bit at a loss as none of these solutions seems optimal, and discarding 10% of the patients would be really sad.

Best wishes,
Herberto Dhanis
