clone2vec 0.1.0

Package for an analysis of lineage-tracing scRNA-Seq data

clone2vec

clone2vec is a Python package for analysis of lineage tracing coupled with single-cell RNA-Seq.

The main key of the package are clonal embeddings — vector representations of the whole clones in low dimensional space. These representations is a dropout-robust and cluster-free way of representation of heterogeneity within clonal behaviour for cell type tree-free hypothesis generation regarding cells' multipotency.

clone2vec builds representation of clones in exact same way with popular word embedding algorithm — word2vec — via construction two-layers fully connected neural network (it uses Skip-Gram architecture) that aims to predict neighbour cells clonal labellings by clonal label of cells. As a result, clones that exist in similar context in gene expression space will have similar weights in this neural network, and these weights will be used as embedding for further analysis.
