Hi Tricia
did you check the tal xform? It is the basis of the ICV. If it looks good then something else is wrong. If that's the case, upload the dataset and we'll take a look Bruce

Hi,
I tried to use the white matter bug fix using v4.4.0 for data that was
originally run using v4.0.4. I then noticed that the IntraCranialVol measure in wmparc.stats and aseg.stats for one of the subjects was -2083.23 (after rerunning recon-all -segstats -wmparc). Is this due to the new way of calculating TIV (as of v4.3.0)? Should I revert back to using the values prior to the bug fix?
Here is the bugr info if needed:
FREESURFER_HOME: /fslhome/mendy22/freesurfer4.4.0
Build stamp: freesurfer-Linux-centos4_x86_64-stable-pub-v4.4.0
RedHat release: CentOS release 5 (Final)
Kernel info: Linux 2.6.18-53.1.14.el5 x86_64
cmd line executed: recon-all -s <subject_id> -segstats -wmparc
Thanks so much,
