Correction: each label was thresholded to have the same area as the average area across ex vivo subjects. The thresholds are different based on how spread out the distribution is.

Hello,

I ran a batch in order to tabulate the FreeSurfer stats from our data set, but error logs indicated that the usual "?h.BA.stats" files were missing. It appears that these files were not generated, and instead we have "?h.BA_exvivo.stats" and "?h.BA_exvivo.thresh.stats". So I am not exactly sure what these are, but a mail archive search suggested that these are associated with the developer version of FreeSurfer? ...or perhaps this is just something new in FS Version 6.0.0?

We are currently running: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c

Any advice appreciated...

Best Regards,

Jason

Hi Jason

I would use the thresholded version. The unthresholded includes every vertex that has a nonzero probability of being in the BA, no matter how small

Hi Douglas, thanks for the information…

Is it the thresholded or un-thresholded version of the "BA.exvivio.stats" that we should generally use now?

I am clearly perplexed - is there perhaps a wiki page or paper that describes the changes to BA stats output in v6.0?

Thanks again, Jason
