Hi Jenifer,
how are you getting those intensity values?

Hi, Running fsv405 on RHEL5. I've encountered some unexpected numerical values wrt FreeSurferColorLUT.txt. Are my expectations off?
- In the aparc+aseg.mgz file, intensity values for the cortical labels range from -32768 to 654, with negative values falling in some regions in the left hemisphere.
- Identical results are obtained if mri_aparc2aseg is used to generate an output file: mri_aparc2aseg --s mysubject --o ./aparc2aseg.mgz
- Values of aseg.mgz map perfectly well to FreeSurferColorLUT.txt
Example values obtained from aparc+aseg.mgz are listed below: lh.superiortemporal=484 (expecting 1030 from FreeSurferColorLUT.txt) rh.superiortemporal=32767 (expecting 2030)
Although these numerical values do not match the LUT, they are consistent across subjects.
Many Thanks for any insights... Jenifer
