Hi Anderson,
First, thank you SO much for your thoughtful and detailed reply. I really appreciate your time. As regards my specific case, I do have access to my pilot data, and have run basically the exact analysis I would like to run in the proposed study, but in a much smaller sample. My follow up question (apologies if it is very naive) would be how, practically, to obtain the inverse cumulative distribution function of the permutation distribution of TFCE from my data. In other words, what tools/commands might I use, and on which outputs from randomise?
I have two types of analysis: surface-based analysis with FIRST (so randomise with the --T2 option) and volumetric analysis (-T) option. I am not sure if the --T2 and -T cases would require different approaches. My primary interest is in F-statistics generated from these analyses.
I really appreciate your help & feedback.
