Hi,
I would suspect that ECG and respiration artefacts would go into their
own respective components, anyway. If you ran single-session ICA on
each set, you could provide melodic with the resp. regressors and
identify the components best correlating with them (see the table
below the images). You could then remove these components from the
single session data with fsl_regfilt before feeding the data into a
concat ICA. I've never tried this, however, and couldn't tell if it's
worth the hassle. Maybe there are other opinions on that?!
Cheers,
Cornelius
