External Email - Use Caution        

Hello FreeSurfer team,

Thank you for providing the recon-all patch. We have applied this to four studies and have seen a notable difference between in the representation of entorhinal over perirhinal on the right hemisphere labelling on each analysis ran. The left hemisphere appears to have less overlap.

I have attached a screenshot of both hemispheres to demonstrate. Would really appreciate any feedback. Thanks!

Cheers,
Yi-Leng

Hi Yi Leng, there’s a recon-all patch for 6.0 at https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/6.0.0-patch/recon-all. You can update it with:

 

cd ${FREESURFER_HOME}/bin

mv recon-all recon-all.backup

curl https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/6.0.0-patch/recon-all -o recon-all

chmod +x recon-all

 

Let us know if that works!

 

thanks

Andrew

thanks. It is almost certainly a bug in recon-all. I'm testing a fix
tomorrow and hopefully we can have one out to you (and the rest of the
list) by tomorrow.

Sorry!
