singleCellHaystack
⚠️ We updated singleCellHaystack in late 2022. The master branch on GitHub is now the updated version 1.0, described here. The version on CRAN is also this updated version. For the older version described here, please use branch “binary”. ⚠️
singleCellHaystack is a package for predicting differentially active features (e.g. genes, proteins, chromatin accessibility) in single-cell and spatial genomics data. While singleCellHaystack originally focused on the prediction of differentially expressed genes (DEGs; see here), we have updated the method and made it more generally applicable (see Sci Rep). It can now also be used for finding differentially accessible genomic regions in scATAC-seq, DEGs along a trajectory, spatial DEGs, or any other features with non-random levels of activity inside any input space (1D, 2D, or >2D). It does so without relying on clustering of samples into arbitrary clusters. singleCellHaystack uses Kullback-Leibler Divergence to find features that have patterns of activity in subsets of samples that are non-randomly positioned inside any input space.
For the Python implementation, please see here.
