Solely inspired by Atbrox's list of academic papers for Mapreduce & Hadoop Algorithms. Unlike computer science where applications of Mapreduce/Hadoop are very much diversified, most of published implementations in bioinformatics are still focused on the analysis and/or assembly of biological sequences. As usual this list will be updated time to time. If you find that any important paper that is missing from the list then please drop a comment at end of the post.

Review articles

1. An overview of the Hadoop/MapReduce/HBase framework and its current applications in bioinformatics

Paper describes the concepts behind Hadoop and the associated HBase project, and current bioinformatics software that employ Hadoop.

Sequence analysis/assembly

2. PeakRanger: A cloud-enabled peak caller for ChIP-seq data

PeakRanger paper describes a Hadoop version with supports for splitting the job by chromosomes to take advantage of the chromosome-level independence (CLI) of ChIP-seq data sets. In the CLI case, "map-then-reduce" becomes "split-by-chromosome-then-call-peaks" where chromosomes are used as keys.

1. Quake: quality-aware detection and correction of sequencing errors

Hadoop cluster was used for Counting k-mers and also to sum together the partial counts computed on individual machines using an extension of the MapReduce word counting algorithm.

2. Biomedical Case Studies in Data Intensive Computing

Study illustrates two use case, one the analysis of gene sequence data (35339 Alu sequences) and other a study of medical information (over 100,000 patient records), and compares the performance of MapReduce computing model with MPI.

3. Cloud-scale RNA-sequencing differential expression analysis with Myrna

Myrna is a cloud-computing pipeline for calculating differential gene expression in large RNA-Seq datasets. Myrna is designed with a parallel Hadoop/MapReduce model in mind. Myrna can be run on the cloud using Amazon Elastic MapReduce, on any Hadoop cluster, or on a single computer (without requiring Hadoop).

4. Cloud computing for comparative genomics

Describes a typical comparative genomics algorithm, the reciprocal smallest distance algorithm (RSD), to run within Amazon's Elastic Computing Cloud (EC2).

5. BlastReduce: High Performance Short Read Mapping with MapReduce
