Scripts for handling Unique Molecular Indexes in Fastq and Bam files, primarily for de-duplication purposes.
Visit the documentation page for more details.
Unique molecular indexes (UMIs) are short, random, nucleotide sequences incorporated into next generation sequence reads for uniquely identifying biological molecules of RNA or DNA. This aids in distinguishing biological duplicates from PCR-derived or technical (optical) duplicates.
This package of scripts aid in processing these UMIs, both from Fastq and Bam files. Embedded UMIs can be extracted from the primary sequence read in a Fastq file, or they may be provided as a separate Fastq file. They may be stored either appended to the read name or assigned to SAM/Bam attribute tag.
These scripts are designed to be fairly simplistic and work as quickly as possible. Users needing more advanced tools or reporting may need to look elsewhere.
See the documentation for more information, including installation help, suggested usage, and a list of applications.
