cardelino contains a Bayesian method to infer clonal structure for a population of cells using single-cell RNA-seq data (and possibly other data modalities).
In its main mode cardelino requires:
-
An imperfect clonal tree structure inferred using, for example Canopy, from bulk or single-cell DNA sequencing data (e.g. bulk whole exome sequencing data).
-
Single-cell RNA sequencing data from which cell-specific somatic variants are called using, for example cellsnp-lite.
You can install the release version of cardelino from BioConductor:
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("cardelino")The development version of cardelino can be installed using the
remotes package thus:
# install.packages("remotes")
remotes::install_github("single-cell-genetics/cardelino")The best place to start are the vignettes. From inside an R session, load
cardelino and then browse the vignettes:
library(cardelino)
browseVignettes("cardelino")The donor demultiplex function, named Vireo, was previously supported in this R package, but now has been re-implemented in Python, which is more memory efficient and easier to run via a command line. We, therefore, highly recommend you switch to the Python version: https://vireoSNP.readthedocs.io.
The vireo function is not supported from version >=0.5.0. If you want to use the R functions, please use the version ==0.4.2 or lower. You can also find it in a separate branch in this repository: with_vireo branch or use the donor_id.R file directly. However, using the Python implementation of Vireo is strongly recommended.

cardelino is almost an anagram of "clone ID R" and is almost the same as the
Italian for "goldfinch", a common and attractive European bird, pictured below
and used in cardelino's hex sticker. In the Western art canon, the goldfinch
is considered a "saviour" bird
and appears in notable paintings from the Italian renaissance
and the Dutch Golden Age.
Perhaps this package may prove a saviour for certain single-cell datasets!
