[Freesurfer] Custom Segmentation of the Cortex usable with mri_compute_volume_fractions

Hello, I would like to generate a custom segmentation of the cortex. That segmentation should be restricted to a certain labeled region (e.g. a Brodmann Area). If possible I would also like to restrict the region to the lower half or upper half of the cortex. Let's call these new segmentations

Hi Caspar, In freeview, once you load a overlay onto a surface, you can click on "Configure" button under "overlay" settings on the panel to adjust overlay display. There is a colorwheel option in it. From command-line, it can be activated like this: freeview -f lh.orig:overlay=lh.thickness:

It might be that the design matrix is ill-conditioned. Did it print anything to the terminal? Also, we are not really supporting qdec anymore, so you can try using the command-line stream (ie, mris_preproc, mri_surf2surf, mri_glmfit, mri_glmfit-sim) On 9/10/19 2:36 AM, James Karantonis wrote: >

When you run rtview, it will run tksurfer. To get to the color wheel, open View->Configure->Overlay, then select "Color Wheel" under the "Color Scale" tab. On 9/10/19 4:03 AM, Caspar M. Schwiedrzik wrote: > > External Email - Use Caution > > Hi Doug and Roupeng, > did you already have th

If you are going to assume a shape to the hemodynamic response, then I don't think it makes much difference. It will make a difference if you are going to use an FIR. On 9/9/19 10:49 AM, Nasiriavanaki, Zahra wrote: > Hi Freesurfer experts > > I have a question about designing an event related ta

The FIR assumes that your stimuli will be presented on a "clock", eg, on a TR (not necessarily ever TR, but every time a stimulus is presented, it starts on a TR). The "tick" of the clock can be the TR or it can be an integer divisor of the TR (eg, TR/2 TR/3). The finer you make it, the more fl
