Hi Bruce:

I looked at the brainmask.mgz and wm.mgz - obviously the pial is not included in superior & middle temporal regions in the brainmask.mgz and in the wm.mgz. The wm intensities are ranging from 96 - 106 in the missing superior & middle temporal regions in the brainmask.mgz. I have attached the brainmask.mgz, wm.mgz, aseg.mgz & aseg+aparc.mgz, all  with pial, white and orig surfaces overlaid.

As mentioned earlier, I had control points added in wm of excluded temporal regions and ran this  command again ( to fix pial surface ) :

recon-all -autorecon2-cp -autorecon3 -subjid subject


The final image did not include the excluded temporal region after opening up in:

tkmedit subject brainmask.mgz lh.white -aux T1.mgz -aux-surface rh.white



But  gave me different values for entire regions in lh & rh aparc and aparc.a2005.stats - cov >1%  in all regions. For example,

                                         
                                             Before adding control point       After adding control point    COV

lh superior temporal(mm2)              3487                                       3102                           8.3%

rh superior temporal (mm2)             3434                                        3370                         4.9%      

lh middle temporal(mm2)                 3902                                        3001                        18.5%

rh middle temporal (mm2)                3046                                       3528                       10.4%


Another question:

if you run this command > recon-all -autorecon2-cp -autorecon3 -subjid subject <  Do we run the entire subcortical segmentation as well?

I appreciate your suggestions.

Deepa.
