FSL -
I want to do Melodic Group ICA. I have a study with 3 groups (schizophrenic, control, relatvive). There are 3 epi session-blocks per subject (N = 92) that are randomized by task block (N=3); each task block has sequential trial order.
1. Do I want to do Tensor ICA by temporally concatenating the sessions within each subject such that the 3 blocks A,B,C are concatenated in the same order for each subject, and my input will be 1 per subject N=92? It seems from previous posts that this may not be the best approach; instead I should put each session-block as an individual input and use multi-session temporal concatenation?
2. I have 4/92 subjects that only have 2/3 sessions. Can these subjects be included? Or must all subjects have the same number of blocks for the analysis?
