DUBStepR

DUBStepR is an algorithm for feature selection based on gene–gene correlations. A key feature of DUBStepR is the use of a stepwise approach to identify an initial core set of genes that most strongly represent coherent expression variation in the dataset. Uniquely, DUBStepR defines a novel graph-based measure of cell aggregation in the feature space (termed density index (DI)), and uses this measure to optimize the number of features.

DUBStepR requires R version >= 3.5.0.

DUBStepR is available as an R package on CRAN (https://CRAN.R-project.org/package=DUBStepR), and is well documented for easy integration into the Seurat pipeline. The source code is also freely available on GitHub (https://github.com/prabhakarlab/DUBStepR).
