Hi,
Can someone please explain to me why we need to select "Multi-session temporal concatenation" for resting-state data? In the Melodic help webpage it says that we should use this approach if we "can not assume that the associated temporal response is consistent between sessions/subjects." But resting-state sequences normally have a fixed scanning duration, and this is the same for every subject. And what if I want to use fsl_regfilt denoising, which requires the single-session ICA approach? Is this not possible with resting-state data?
For the "Multi-session Tensor-ICA" approach the webpage says "It is recommended to use this approach for data where the stimulus paradigm is consistent between session/subjects.". But why should we assume that the temporal response is consistent between sessions/subjects in task fmri? Some subjects might have had longer scanning times or they might engage the task very differently.
Thank you for your help
Sam
