when I try and import my .nrrd files as sequences (which they work in slicer 5.8.1) i get an error that slicer cannot read it. They will import as volume but then there is no way to change the colour map, i have tried the way you do in slicer 5.8.1. When i change the colour map it only change the legend bar. The only time the actual colours change is when i click on the presets, it always automatically imports as the rainbow scheme.
Thanks for reporting. Perhaps it’s related to these changes, @cpinter ?
@gchampa can you share a sample dataset that loads differently between the two versions?
