Hi Yi-Leng
the annot file contains the label with the max p-value at each location.
The thresholded .label files are computed to have the surface area that
matches the average of the training labels, so they will not be the same.

External Email - Use Caution
Dear FreeSurfer Developers,
Prior to extracting the gray volume numbers of the entorhinal and perirhinal
cortex from
?h.BA_exvivo.thresh.stats file, I was examining the entorhinal and perirhinal
cortex on the
?h.BA.thresh.annot on Freeview. However, I noted that their locations on the
annot file did not
correspond to the (non-overlapping) locations indicated by
?h.entorhinal.thresh.label and
?h.perirhinal.thresh.label.
I have also loaded the annot files and label files from the fully recon-ed subject named
"bert" on
Freeview and observed the same mismatch in the labeling. I am curious why this
might be the case.
I have searched the archive and have not been able to find any similar queries
on this, hence it would be
of tremendous help if someone could clarify this observation. If it is of
interest, I am running
freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0 on Ubuntu 16.04.
Thank you for your assistance and I look forward to hearing from you.
Best regards,
Yi-Leng
