Dear Experts: We have acquired rfMRI dataset with A-P and P-A phase encoding direction and the data was acquired in eight 5-minute runs split across four imaging sessions. We have processed the data using HCP pipelines (e.g., PreFreeSurfer, FreeSurfer, PostFreeSurfer, fMRIVolume, fMRISurface and ICA+FIX). So we have results for each run of rfMRI data.
I’m just curious about what is recommended way to combine each run of data (e.g., rfMRI_REST1_AP, rfMRI_REST1_PA, …, rfMRI_REST4_AP, rfMRI_REST4_PA). Can we just temporally concatenate each run of data before running ICA+FIX? Or can we do group ICA using each data processed with ICA+FIX? What is the optimal way to do combining analysis across each run? Any insights would be greatly appreciated. Thanks.
