RE: [Freesurfer] average thickness

Great, thanks. One more question. Doing it the mris_glm way, is there somehow I can turn the beta files (bfloat) into ascii surface format? Thanks, -Aaron- ________________________________ From: Doug Greve [mailto:greve@nmr.mgh.harvard.edu] Sent: Thursday, January 05, 2006 3:08 PM To: Goldman, Aaron (NIH/NIMH) [F] Cc: freesurfer(a)nmr.mgh.harvard.edu Subject: Re: [Freesurfer] average thickness The easiest way is probably to build an average subject (make_average_subject). This will create ?h.thickness in the surf dir which will be the average across the input subjects. You could also use mris_glm with a design matrix of all 1s. The beta output will then be the average thickness. Goldman, Aaron (NIH/NIMH) [F] wrote: Hi, I feel like I used to know this, but how do I make a map of average thickness for a group of subjects?

Question re' intervention in result of parcelation
by zvalim＠gmail.com 05 Jan '06

05 Jan '06

Hello all, I have a conceptually simple task to accomplish, but can't seem to get it to work via the tkSurfer interface. My goal is to take the result of Freesurfer's default parecelation scheme, remove the Superior Temporal Sulcus label, and partition what was STS into 3 separate regions, with 3 separate labels. Removing the STS label, and generating a new partition of that area into 3 separate labels works OK on the GUI. But I run into problems when trying to save the new partition. First, if I don't assign the new labels to a Structure in the "labels" window, the editing is not saved. However, if I do assign these labels to a structure (e.g., the S_temporal_superior structure) , then after "exporting" the new annotation and reloading it, all three labels will appear as one region called S_temporal_superior. In short, I can't find a way to export the results of my ROI edits into a .annot file. I suspect I might have to create three new structures that correspond to the new labels, but I am not sure in which file I should intervene to create new structures. Any help, much appreciated. Oori

Hi, I am using tkregister2 to register two perfusion volumes. I can adjust the brightness of the movable volume, but don't know how to adjust brightness for the target volume. Is this possible? Thanks, Vasanth --

I am loading the GDF file from the menu interface. Tksurfer runs correctly before loading the file, including when I load an overlay, but it quits immediately after loading any GDF file. >>> Kevin Teich <kteich(a)nmr.mgh.harvard.edu> >>> Are you loading the GDF file from the menu interface, or from a commandline tool?
