Re: [Freesurfer] Volume maps unit in FreeView

Thanks Dr. Greve. That makes sense if the color bar in FreeView represents vertex-wise volume and area for ?h.volume and ?h.area respectively. Actually, 20-40K mm^3 (i.e. 20-40 cm^3) volume range I extracted is for Yeo networks, I guess thats why this range is much higher compared to vertex-wise

When you say volume maps, I assume you are talking about the ?h.volume file produced by FS. In that case (assuming you have not scaled the the eTIV), then that is "volume of a vertex" in mm3 (for surface area it is in mm2). Not sure what you mean about the actual volume values in the 20-40k

Hi, I have a very simple question. I have cortical volume maps (averaged over 30 subjects). I can view those in FreeView using lh.pial overlaid with lh.mean.volume.mgh file. In overlay > configure option, I had to set the min as 0 and max as 4 to display the average volume. Now the color bar is
