Great point. Because insitutype for RNA uses a negative binomial model, it's stuck with using integers. That said, the new Protein mode - coming in days - runs with a Gaussian model. It could easily be run from proseg outputs.
Currently, InSituType takes only raw count matrices. This is logical, since scaling or transforming data might differ per dataset. However, the inability to take count matrices consisting out of floats instead of integers limits the use of InSituType to some extend.
Arguably, proseg is a way of improving segmentation data. https://github.com/dcjones/proseg , after proseg, an expected-count matrix is provided. This consists out of floats, but should still be considered 'raw' counts before any further normalisation. Proseg has the ability to force integer counts (--output-maxpost-counts), however it might also be useful to be able to take float count matrices into InSituType processing
