And after creating the mgh volume, how can I read it? Is it possible to open it in tksurfer? Should I load it as an overlay? I've used one of my already pre-processed subjects, created a 'vol' with the same number of vertices of one of the hemisferes, and saved the output of save_mgh file as an

That looks exactly right. Are you experiencing a problem? I assume that uS1_v01_06LOC_x001.img is a mean functional image of some sort (and not a contrast image). Did you check the registration? doug Johannes Klackl wrote: Dear all, I'm currently trying to conduct a surface-based group

Re: [Freesurfer] optseq2 question about fixing null intervals

2007-08-06 Thread Doug Greve
what do you mean by allowable null intervals? If you mean that there needs to be a fixed amount of time between two stimuli, then you cannot use optseq for this. However, you can tell optseq that there are only two stimuli, which each stimulus is a pair. Then you'd have to go back and recode

I was just wondering why the banks of the superior temporal sulcus was made into its own label on the Desikan template. Does this correspond (roughly) to a particular functional area. I didn't see anything in the paper about why it was chosen. Is it just easy to define given sulcal/gyral

Hi Bruce, I see. It just seems to be surrounded by very large parcellation units that haven't been divided. Does it have good landmarks to place it along the sulcus? Cheers, -Morgan Bruce Fischl wrote: I think it's where Ron Killiany previously found large effects in prodromal AD. On
