Extracting the individual or average cortical thickness value of significant cluster after multiple compression correction by FDR.
Dear FreeSurfer Experts:
I have question regarding extracting the individual or average cortical thickness value of significant cluster after multiple compression correction by FDR. For example I have 100s of subjects in an analysis and several blobs showing significant difference between groups after FDR, how do I export mean or individual subjects cortical thickness values for significant blob? I can click on each data point and copy the terminal readout or create an ROI, map label to subjects and export it out but both approaches are time consuming and prone to human error. Is there a way of using existing QDEC setup files to export all this data out more cleanly?
With best Regards, Santosh
This is not an easy thing to do in QDEC. An alternative is to run mri_glmfit-sim on the QDEC output folder, setting the thresholds to the same that you used in QDEC. mri_glmfit-sim will compute means foreach subject and cluster.
