Research software

Tools for exploring biological data, from single cells to spatial tissues.

Spatial transcriptomics

SpaHDmap

Interpretable, high-resolution dimension reduction through the integration of spatial transcriptomics and histology images.

  • Multimodal learning
  • Multiple spatial datasets

Single-cell integration

scINSIGHT

A matrix factorization model for analyzing single-cell samples from different biological conditions, including disease phases, treatment groups, and developmental stages.

  • Shared and condition-specific patterns
  • Batch correction
  • Automated parameter selection

Adaptive clustering

scAce

Jointly learns cell embeddings and cluster assignments with a variational autoencoder and adaptive cluster merging.

  • Adaptive embedding and clustering
  • Large-scale scRNA-seq

Graph representation learning

scBiG

Learns cell and gene embeddings from a cell–gene bipartite graph using a graph autoencoder.

  • Cell–gene relationships
  • Biological structure preservation
