Hi Satra,
there is a random element to it. The GCSANclassify: could not find GCS for node 0! was a bug that somehow got into the atlas, and has been fixed.
Do the outputs look pretty much the same?
cheers, Bruce

I'm noticing some discrepancies between the 64 bit and the 32 bit version of mris_ca_label. I've shown the output from the 64 bit version and the 32 bit version operating on the same subject. I'm using are the dev versions for centos from the download site.
To note:
- In the 64 bit version I get the following output during the process:
GCSANclassify: could not find GCS for node 0! Numerical result out of range
The 32 bit version does not generate this error on either on th 64 bit machine or a 32 bit machine.
- The numerical values listed for changed and examined are different. This
could well be the case if there was some random element being used.
Thanks,
Satra
