External Email - Use Caution
Hi Agnieska, sorry for the delay. It looks like the contrast is slightly different than FS expects. I ran it with the -3T flag (which changes the talairach atlas), and it seemed to run fine on that subject. Try it out._______________________________________________

Dear Doug,I uploaded the data by ftp in Windows 10 on 1st Aug. I hope You can see a tar file. The file's name is HTN_Con_096 and it contains the subject's folder after recon_all. Do You need any other data?All the best

That is a little strange. Can you tar up the data and upload it to
ftp://surfer.nmr.mgh.harvard.edu/transfer/incoming
Let me know when it is there and what the file name is
