maplesword/RefSimSpec:

This package is built to calculate the transcriptome similarity spectrum given a reference set (RSS). It is designed to calculate RSS for brain organoid single cell RNA-seq data to the human developing brain RNA-seq data in Allen Brain Atlas, in order to reduce data dimensions, denoise data and assign region information to cell clusters. It can be used for other purposes, by changing the referene set to a custumized one.
