Hi AFNI experts,
So I have a slightly complicated problem, which I’m hoping I can get help solving.
I’ve been using FATCAT to perform my functional connectivity analysis, however, when I get to the statistics part (3dMVM) I get errors. It seems that I can’t perform this on a large dataset.
To give you an idea of my dataset: I have 750 subjects that I’m studying and 4 functional networks for each and each network has 7 ROIs, which I realize can be computationally intensive. I want to make comparisons between my healthy and depressed patients.
My question is what other approach can I use to perform a statistical analysis if it’s not 3dMVM? And what should I do?
I was thinking of doing an ROI comparison test of some sort, but I was told to try and combine ROI’s to get a mean value for each network. I’m really confused.
Any advice/suggestions would be greatly appreciated.
