Dear List I get the following error: „550 Failed to change directory.” I tried on two operating systems. The wget also doesn’t work. Says the file doesn’t exist. Do you get the same errors, or is it specific to my system? Best Lau ___ Freesurfer

By using --sfmt curv and --tfmt curv you are saying that the input and output formats are curv. But they are nifti. Try removing the --sfmt and --tfmt (it will automatically detect that they are nifti) doug On 8/18/14 10:40 AM, Matthieu Vanhoutte wrote: Dear experts, I try to project on

Sorry to interrupt. I have a relevant question about the correlation analysis. If the age has been controlled for when surface-based analysis is done, do we need to controll for age again when we do subsequent correlational analysis in SPSS? On Tue, Aug 19, 2014 at 5:01 PM, Douglas Greve

Hi Bastian, yes, I have some code to do what you want. You would duplicate and flip the good hemisphere in the image and then run FS on the symmetric heads. This can be done via robust_register and (mis)-using the mid space. You can find some description of this procedure here: *Robust and

Hi Bastian, this is in cases where you need to make the images symmetric so that recon-all processing works, but then do the analysis on the original (non flipped) hemisphere in each subject. You should not use this to do a point wise comparison between left (original healthy) and flipped

Hello Alex, I created the FreeSurfer VM and you are correct that the Virtual Box host is 32bit. I cant remember exactly why I did it that way, but I suspect it may have been in an effort to reduce overall size, as the gzipped size of the .vdi file is 9gigs. Also, it was created more as matter
