My specialization is in signal processing and machine learning. I am not sure about ICA based time series. If we consider 100 ICA components, how can we define each node name for graph theoretical measures? For example, the paper ‘Chronnectomic patterns and neural flexibility underlie executive function” [Jason et al. NeuroImage 147 (2017): 861-871] talked about 100 components. They define DNN, subcortical, frontal, etc. networks. Can you give me any reference that can guide which component belongs to which network or how to name them? If somehow, I discover connectivity between Component_1 and Component_3 is significantly related to some behavior, how can I express it in neuroscience term? I believe my question is clear now.

Particularly that gyral/sulcal folding-based parcellation would be able to answer? If you want a neuroanatomical parcellation into cortical areas, this is available here: https://balsa.wustl.edu/file/show/3VLx Matt.

I don’t want to use ICA based time series because they cannot answer lot of neuroscience question. I prefer ROI based analysis. A 45+ ROI template would be useful (e.g. FreeSurfer template). Is it possible to use workbench on processed data to extract ROI based time series, or I have to run FreeSurfer on data? Please help me with some guidance and reference.
