Hi all: After finishing recon-all steps, there are some thickness files generated such as lh.thickness and lh.thickness.fwhm10.fsaverage.mgh which contain cortical thickness values at each vertex. Are the thickness values in lh.thickness file calculated in individual space ,that is , they are absolute values and values in lh.thickness.fwhm10.fsaverage.mgh file computed based on fsaverage template, that is, they represent relative values ? Any suggestions appreciated.
They are all absolute in the sense that they are in real millimeters Bruce
