External Email - Use Caution
Hi all,
I am deeply confused and terribly needed some help, and I failed to find the answer in the Freesurfer website.
I had two patient groups F and R. To analysis the correlation between active time and cortical thickness, I tried two different methods A and B (A, treating patients in different group F and R as shown in attached figure A; B, treating all patients as one group FR as shown in attached figure B), and got distinctly different results.
So, my questions:
1、Which one is actually correct for calculating the correlation between active time and thickness, and what does the other one mean?
2、Does "--cache 3 abs --cwp 0.999" means that the result is only corrected with vertex level P < 0.001, and no cluster level correction is conducted?
I am looking forward to getting your help.
Sincerely yours,
Ge Tan
