[Mrtrix-discussion] Mrstats question

Hi

I've just started to use mrtrix and have a couple of questions about the mrstats function. Firstly, do the min and max results refer to the lowest and highest FA values in the voxel mask I'm running the function on? The function consistently reports min values well below the FA cutoff i've used in generating my tracts, often below 0.05. Secondly, the max value is occasionally >1.0. Looking at the FA maps I'm generating on mrtrixs I occasionally see voxels with FA values >1.0. I think this may be related to noise as the voxels are in regions where diffusion is very restricted in one direction. Is there anyway of correcting for this?
Thanks in advance for your advise
