thanks Bruce

External Email - Use CautionHello Bruce, Thank you very much for your quick response.
I do have another point of confusion regarding the BA.thresh.annot file.
When visualised in Freeview (using Bert as
the example), the BA.thresh annotation file labelled the medially
located structure as the perirhinal cortex and
the laterally located structure as the entorhinal cortex.
I find that quite puzzling as I understand their relative anatomical
location to be the reverse; I would really
appreciate it if you could clarify why it is labelled as such in the
annot file?
Again, thank you for your time in helping me understand this.
Cheers, Yi-Leng

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