Hi Freesurfer Team,

I am running recon-all on Freesurfer version 6. A few of my subjects have “XL defect detected …” and their recon-all have been running for more than 20 hours. I hope this is not a silly question, but will this XL defect be corrected eventually…? 

Another question, what are “defects”? Is there anything I could do to the raw T1 before recon-all?

Thanks!

Shane
