| - | Finally, you may want to extend your ROIs through the cortical depth. Note that by default you are looking at the midcortical depth (See Cortical Depth slider on the main viewer). If you want your ROIs to extend through the gray matter, you can ROI/Convert/Convert cortical depth. You want to Project through depth, and then starting at your current depth (0.5) copy the ROI through the whole gray matter. So you set referenceDepth to 0.5 and then starting at 0 (minDepth) go in increments of 0.1 (depthStep) until reaching the maxDepth of 1, adding voxels that are in the same location to the ROI. Be aware that if you extend too far with your ROI, you may start to cross sulcal boundaries, so use this tool carefully: | + | Finally, you may want to extend your ROIs through the cortical depth.

Also, this tool will only convert voxels if they exist in the currently displayed flat map - so if you want to do rois on the other hemisphere, you will have to switch to the other hemispheres flatmap and convert those rois separately: |
