-rank option in dwidenoise


Thank you very much for your continuous support to MRTrix3 users.

We are curious about -rank option in dwidenoise, which is descriped in documentations.

However, it seems that this option does not appear in the MRTrix3 installed in our computer server. Is that the problem of updating or is this option not yet available to the community?

In general, we are interested in comparing the output of denoising when different cutoff was used. Is this option (-rank) the right one to use when we use different cutoff? What is a default parameter used for this -rank option?
