SnapATAC (Development)

SnapATAC (Single Nucleus Analysis Pipeline for ATAC-seq) is a fast and accurate method for analyzing single cell ATAC-seq datasets. SnapATAC 1) overcomes the limitation of reliance on population-level peak annotation, 2) improves the clustering accuracy by integrating "off-peak" reads, 3) controls for the major bias using a regression-based normalization method and 4) substantially outperforms current methods in scalability.

SnapATAC has two components: Snaptools and SnapATAC.

  • SnapTools - a python module for pre-processing and working with snap file.
  • SnapATAC - a R package for the clustering, annotation, motif discovery and downstream analysis.

Install snaptools from PyPI. See how to install snaptools on FAQs.

$ pip install snaptools

Install SnapATAC R pakcage (development version).
