Hi FSL experts,
I was wondering how to do a correlation analysis between subjects' RSNs functional connectivity and test scores. For example I've got 10 subjects and has identified 12 resting-state networks using melodic ICA, one of them showed significant reduced functional connectivity compared to health controls, now how can I do to find out if this reduction positively or negatively correlates with i.e. MMSE scores? Can I achieve this within FSL or how can I extract the data (values) needed and do analysis in other statistic softwares?
Generally thinking we'll be needing each subject's specific network (component) data and corresponding MMSE score, so which value in the ICA or dual regression output is the one that represents functional connectivity?
A lot questions..
Thank you in advance.
