Hi everyone

I have several series (6 rodents species) of microCTs, that I cannot save in DICOM format. I can only reconstruct the slices in TIFF, BMP, PNG format (I’m using NRecon software).  
When I load the series of each rodent, all images appear in separate master volumes. I tried to use Merge volume function, but they still appear as separate, I can’t merge separate volumes into one.  
What should I do? I want to use Slicer but with this problem is useless.

Kind regards

Guido

I use Slicer with datasets from Nrecon daily.

Make sure to uncheck “single file” option during data. See my blog for more detailed instructions using Slicer with image stacks  
[https://blogs.uw.edu/maga/2017/04/11/a-worked-example-getting-and-visualizing-data-from-digimorph/](https://blogs.uw.edu/maga/2017/04/11/a-worked-example-getting-and-visualizing-data-from-digimorph/)

You can also convert your stack outside of Slicer to a 3D format (nifti or NRRD) and load it.
