Other applications

  • BASIC - [python] - BASIC is a semi-de novo assembly method to determine the full-length sequence of the BCR in single B cells from scRNA-seq data.
  • CIPR - [R] - (Cluster Identity PRedictor). A Shiny web applet that helps annotating the cluster identities in single-cell RNA-sequencing (SCseq) experiments. In short, the algorithm compares gene signature of experimental clusters with the gene signatures of sorted mouse immune cell populations obtained from ImmGen database, and calculates an aggregate identity score for each cluster. For the calculation of the identity score, the magnitude of the differential expression in both upregulated and downregulated genes is taken into account. By this approach, CIPR aims to enable researchers to quickly and objectively annotate the biological identity of the cell clusters in SCseq data. Source code is accessible on GitHub.
  • dropEst - [C++, R] - High-performance pipeline for initial analysis of droplet-based single-cell RNA-seq data (Drop-seq, inDrop, 10x and some others).

  • sircel - [python] - sircel (pronounced "circle") separates reads in a fastq file based on barcode sequences that occur at known positions of reads. This is an essential first step in analyzing single-cell genomics data from experiments such as Drop-Seq. Barcode sequences often contain deletion and/or mismatch errors that arise during barcode synthesis and sequencing, and we have designed our barcode recovery approach with these issues in mind. In addition to identifying barcodes in an unbiased manner, sircel also quantifies their abundances. doi
