[Mristudio-users] Obtaining tract volume data

[melcarr at umich.edu]

Hello,

I'm attempting to calculate mean tract volume for a tract spanning  
between two ROIs in a subject's FA map.

Is it safe to define tract volume as: the number of voxels between  
both ROIs multiplied by the size of an individual voxel?

Does the first measure above ("the number of voxels between both  
ROIs") correspond to the measure "Average Length, mm" in the Fiber  
Statistics window (an example of this window is shown in the User  
Manual, page 26, Figure 19. Fiber-statistics)?

Just wondering, thank you.
