MRtrix3 provides a set of tools to perform various advanced diffusion MRI analyses, including constrained spherical deconvolution (CSD), probabilistic tractography, track-density imaging, and apparent fibre density
If eddy_quad fails, then a text file is written in the scratch directory containing the stdout / stderr contents. However if -nocleanup is not specified, this file is lost, as the script will nevertheless execute to completion. Given that the output directory for the eddyqc_* options is always created (it just won't be complete if eddy_quad is unsuccessful, it will contain only information from eddy), should be easy to write that text file into that directory on eddy_quad failure, so that its failure can potentially be diagnosed.
