Dear Experts,
I have done a between group (2 groups) difference in whole brain voxel based cortical thickness using QDEC, which showed significant regional differences in certain clusters bilaterally in the brain. I also did a correlation between cortical thickness and behavioral scores separately in these two groups. Now, I want to superimpose regions (clusters) which showed positive and negative correlation on the results/ regions I obtained in my between group analysis. How can I do this?
Thanks in advance! Sunil. _______________ Sunil K Khokhar PhD Scholar, Department of Neuroimaging & Interventional Radiology, NIMHANS, Bengaluru, INDIA. khokharsunil1@gmail.com +91-9413101839
are you asking how to create positive and negative regions or are you asking how to operate the visualization?

To operate the visualization and obtain the common regions of my between-group difference results and the correlation results in one image. In other words, overlapping/ superimposing my correlation results on the between-group results (to obtain the common regions from the two separate analysis).

To obtain the common regions, first binarize the clusterwise significance maps with something like mri_binarize --min 2.0 --i clustersigmap1.mgh --o bin.clustersigmap1.mgh Same for the other groups Then take the intersection fscalc clustersigmap1.mgh and clustersigmap2.mgh -o intersection.mgh
