Hello MRtrixperts,

(sorry for the long intro)

Instead of running statistical analysis for every fixel in the brain, I am interested in exploring patterns of covariation in FD across individuals to potentially elucidate the underlying neurobiological processes of these coordinated changes. Thus I am using a data reduction technique to fixel’s FD to look at FD covariance networks. Therefore, for this type of analysis, I did not run the fixelcfestats and stop the fixel-based analysis pipeline at segmenting FODs to estimated FD.

However, for my data reduction technique to work in optimal conditions, I would very much like to use the smoothing procedure implemented in fixelcfestats based on the whole-brain tractography for my FD data.

**My question is: would there be an easy way to add a little code in fixelcfestats to ask it to output the smoothed metrics?**

thanks in advance for your responses/comments/suggestions !

All the best,

Josiane
