 **scAR** (single cell Ambient Remover) is a package for denoising multiple single cell omics data. It can be used for multiple tasks, such as, **sgRNA assignment** for scCRISPRseq, **identity barcode assignment** for cell indexing, **protein denoising** for CITE-seq, **mRNA denoising** for scRNAseq, and etc... It is built using probabilistic deep learning, illustrated as follows:
