Hi there,
I am running a patient vs. control comparison. FEAT with cluster thresholding was missing small subcortical effects I was looking for, but Randomise identified significant clusters in the ROIs I hypothesized. To create a t-map for these clusters, is it appropriate to simply select voxels above an a prior t-threshold (e.g. 2.3) that fall within the clusters that Randomise identified?
I would also like to look at the correlation of activation in these voxels with clinical variables. Whilst there is a tutorial to do this in FEAT, is there a way of using the voxels I identified from the Randomise analyses I described above?
Thanks in advance for your thoughts
Anna
