[Debian-med-packaging] Bug#617342: mriconvert: Intended behaviour for multi-frame images?

[Jolinda Smith]

The intended behavior, of course, is that all frames be present. However, due to the rarity and variety of multiframe data we have not been able to ensure that it works in every case. Unfortunately we don't have the resources right now to address problems that primarily affect users outside of our own institution. I recommend trying the excellent "dcm2nii" converter instead, to see if that works with your data.
