Hi FSL experts,
I am working on some pilot data analysis & power calculations for a grant. I have used FIRST's vertex-based analysis with randomise and the --T2 option to generate some preliminary data, and I would like to use this information to estimate statistical power for our proposed sample size. I am unsure how to do this when the test is permutation-based and with TFCE. I saw this in the archives:
https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=fsl;5844766a.1105
but I am not sure how to apply it, or the degree to which it applies in this case.
Any insights you have will be very useful!
Thanks,
Allison
