infercnvpy: Scanpy plugin to infer copy number variation (CNV) from single-cell transcriptomics data
Infercnv is a scalable python library to infer copy number variation (CNV) events from single cell transcriptomics data. It is heavliy inspired by InferCNV, but plays nicely with scanpy and is much more scalable.
WARNING:
This package is still experimental. The results have not been validated, except in that they look similar, but not identical, to the results of InferCNV.
We are happy about feedback and welcome contributions!
