Functional Connectivity between seeds from ROIs defined in MarsBar
Fri, 02/15/2013 - 23:18 — oguipponi
Hi,
I'm currently analysing Percentage of Signal Change within ROIs defined in MarsBar toolbox and I'd like to explore the functionnal connectivity between those ROIs thanks to REST toolbox. Unfortunalety the ROIs defined in MarsBar are not correctly defined (problem of extension? origin?). Is there a way to convert my MarsBar ROIs into ROIs well defined for seed-based connectivity in REST?
Thanks a lot for your response
Best,

Re: Functional Connectivity between seeds from ROIs defined ...
The ROI files defined in MarsBar could be saved in .nii / .img? Then it could be used.
Another way is if you already extrated ROI time series, then you can use matlab command corrcoef get the correlations easily.
