Project description

Build Status PyPI Code Style

astir is a modelling framework for the assignment of cell type across a range of single-cell technologies such as Imaging Mass Cytometry (IMC). astir is built using pytorch and uses recognition networks for fast minibatch stochastic variational inference.

Key applications:

  • Automated assignment of cell type and state from highly multiplexed imaging and proteomic data
  • Diagnostic measures to check quality of resulting type and state inferences
  • Ability to map new data to cell types and states trained on existing data using recognition neural networks
  • A range of plotting and data loading utilities
automated single-cell pathology
