Hello everyone, I'm conducting an analysis involving a training group and a control group, where each group has a pre and a post scan. I setup the matrix file, the contrast file, and ran mri_glmfit along with mri_glmfit-sim for the cluster correction. The analysis finished revealing a significant cluster, although I want to confirm that my interpretation of the results is correct. I see a significant cluster which I believe means the training group showed greater thickening compared to the controls, is this correct? Also, how can I tell if clusters represent thickening or thinning in the training group compared to the control group?
When I setup the matrix file, I entered 1's and -1's for the control subjects in the first column, and training subjects in the second column. When I setup the contrast file, I entered a -1 and then a 1, with 0's for the rest of the variables. Thanks for the help. -W. Ryan McGarry
