Hello, I would like to report the coordinates of the regions found in my clusters. This is what I did so far. 1- TBSS, followed by randomize (All is well till here). 2- I got my clusters using the autoaq command and the results are 4 clusters. Each cluster has several regions in it. I have the voxel# of the clusters and the coordinates of the clusters. I want to get the coordinate and voxel number of each of the sub clusters. So to get the coordinates I wrote the cluster command with --olmax. Now to name the clusters, I went to atlasquery and used -c for each of the coordinates. Until now I have all the sub cluster coordinates and names, however I don’t know the cluster size of each sub cluster region. Can someone help me know the cluster size of each of the sub cluster region? Also, I have another question. Since in one of my clusters, for e.g., I saw that the superior longitudinal fasciculus (SLF), exists twice. Each having separate coordinates. Also the SLF not only exists twice in the same cluster, but also is a sub region in other clusters Example Cluster 1 1-SLF coordinates 2- Some region coordinates 3- SLF coordinates Cluster 2 1- Some region 2- SLF 3-Some regions coordinates Is it proper to make a ROI (SLF) and try to check how many significant voxels are in that ROI instead of what I did above? If that is okay, how can I do that? E.g. SLF is the ROI To get the # voxels in ROI -Go to FSL view, load the JHU tact atlas SLF, save it as make and binarize it, then how do I get the # of voxels inside that ROI? For coordinates of this ROI, should I just report the local max of SLF itself? If not, how do I get that as well Sorry for asking several Qs.. Thank you in advance, WY
