I am eager to test the improvements @lassoan added in a pull request (see [Convert between MultiVolume and Volume Sequence? - #5 by lassoan](https://discourse.slicer.org/t/convert-between-multivolume-and-volume-sequence/24504/5) for discussion) a few days ago, but the Windows preview build has failed each day since then. Looking at the Cdash error ([CDash](https://slicer.cdash.org/viewBuildError.php?type=0&buildid=2755183)) it doesn’t seem likely to be related to the PR changes, but I don’t know enough to really know.

So, I addressed the original error (git lfs missing), but seem to have found some new ones. Still working on it.

```auto
