how to extract the individual cortical thickness or volume value of significant cluster after RFT correction
Dear experts I have question regarding extracting the individual cortical volume value of significant cluster after RFT correction. I have 209 subjects in an analysis and G_pariet_inf-Angular showing significant correction with score of autism after RFT correction using command of mri_surfrft_jlbr in Matlab, how do I export individual subjects cortical volume values for significant regions ? In addition, I did not analyze it using QDEC and just use command following reference (https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis)Thank you and hope for responses. With best Regards,kangcheng Wang
Dear experts I am sorry. There was some wrong with previous description. The results showed that G_pariet_inf-Angular was significantly positive correlated with score of autism after RFT correction using command of mri_surfrft_jlbr.

Dear experts I run mri_glmfit-sim with the following command : mri_glmfit-sim --glmdir autistic.rh.volume.20 --cache 1.3 ${corr} --cwp 0.5 --2spaces did it right? In the creating files, I found cache.th13.pos.sig.ocn.annot. But I don't know how to load it in to freeview or tksurfer. Could you instruct me how to do it ?
Thank you
You can run mri_glmfit-sim using the same voxel-wise threshold and setting the clusterwise threshold to .5. This will create several files. One will be called something like {csdbase}.y.ocn.annot. Load this in tksurfer or freeview to find which cluster corresponds to your cluster. Then look in {csdbase}.y.ocn.dat. This will be a matrix with number of rows equal to the number subjects and number of columns equal to the number of clusters. Take the column that corresponds to your cluster.
