Hi all and happy new year!
I am looking for some insights about combining regressors obtained with physIO toolbox (Kasper et al., 2017) and confounds from fmriprep (Esteban et al., 2017).
A potential idea would be to use 24 motion regressors from fmriprep + respiratory and cardiac regressors from physIO. However, I saw that WM and CSF confounds are also often added to GLM. So I was wondering whether there is something known about the correlation between WM and CSF confounds and physiological regressors obtained with physIO?
