The goal of alabaster.sfe is to implement a language agnostic format to represent SpatialFeatureExperiment on disk, as in the existing alabaster packages from ArtifactDB. This serves to formalize and standardize the files written to disk when SFE reformats smFISH transcript spots and to improve interoperability between the R and Python implementations of Voyager.

You can install the development version of alabaster.sfe from GitHub with:

# install.packages("devtools")
devtools::install_github("pachterlab/alabaster.sfe")

This package has been submitted to Bioconductor and is under review
