Hi all, I have some troubles with an enhanced dicom files contaning 9-b-values diffusion volume. When loading the Dicom file, in Examine-\>Reader, it is written “Diffusion volume-please see DWI Convert module for advanced options and help”, but DWIConvert does not work on purpose. I would like to open the whole sequence, and also open only one b-value at a time. Thank you for any help

Did you try dcm2niix? It’s available through [SlicerDMRI](http://dmri.slicer.org/). Try the latest nightly.

If that doesn’t work, it would help if you could share an example scan. When you say enhanced dicom files, so you mean [like this](https://www.dicomstandard.org/wp-content/uploads/2018/10/Day1_S9-Solomon-Multiframe.pdf)? Those are fairly new and not too common yet, but it would be great if we could support it.
