RT Journal Article SR Electronic T1 Simultaneous dimensionality reduction and integration for single-cell ATAC-seq data using deep learning JF bioRxiv FD Cold Spring Harbor Laboratory SP 2021.05.11.443540 DO 10.1101/2021.05.11.443540 A1 Kopp, Wolfgang A1 Akalin, Altuna A1 Ohler, Uwe YR 2021 UL http://biorxiv.org/content/early/2021/05/12/2021.05.11.443540.abstract AB Advances in single-cell technologies enable the routine interrogation of chromatin accessibility for tens of thousands of single cells, shedding light on gene regulatory processes at an unprecedented resolution. Meanwhile, size, sparsity and high dimensionality of the resulting data continue to pose challenges for its computational analysis, and specifically the integration of data from different sources. We have developed a dedicated computational approach, a variational auto-encoder using a noise model specifically designed for single-cell ATAC-seq data, which facilitates simultaneous dimensionality reduction and batch correction via an adversarial learning strategy. We showcase both its individual advantages on carefully chosen real and simulated data sets, as well as the benefits for detailed cell type characterization via integrating multiple complex datasets.Competing Interest StatementThe authors have declared no competing interest.
