dropEst - Pipeline

Pipeline for estimating molecular count matrices for droplet-based single-cell RNA-seq measurements. If you use the pipeline in your research, please cite <#citation> the corresponding paper <https://doi.org/10.1186/s13059-018-1449-6>.

News

[0.8.6] - 2019-08-01

-  Added support for Drop-seq and CEL-Seq2

See `Changelog <https://github.com/hms-dbmi/dropEst/blob/develop/CHANGELOG.rst>`__ for the full list.

General processing steps
------------------------

1. **dropTag**: extraction of cell barcodes and UMIs from the library.
   Result: demultiplexed .fastq.gz files, which should be aligned to the
   reference.
2. **Alignment** of the demultiplexed files to reference genome. Result:
   .bam files with the alignment.
3. **dropEst**: building count matrix and estimation of some statistics,
   necessary for quality control. Result: .rds file with the count
   matrix and statistics. *Optionally: count matrix in MatrixMarket
   format.*
4. **dropReport** - Generating report on library quality.
5.  `dropEstR <https://github.com/kharchenkolab/dropestr>`__ - R pacakge for UMI count corrections and cell quality classification
