Hello,
We´ve been using REST to analyse resting state scans.
First we did it following the indications of the presentation, using a mask for the ROI and a mask for the brain.
Well, we finally obtained the default mode networks, as expected.
However, we realized that we had used images with different origins (brain mask, ROI mask and scan images), so we changed this parameter so that the three had the same origin. After doing the analysis with REST again, we were consternated to see a different zmap from the first one, and no default mode network could be seen.
We´d like to know how does REST deal with origin point. Does it take into account the origin of the images or the borders of the brains to overlay the ROI to the scan images? What possible explanation can there be?
Thank you very much,
