  • Title: MeFiT: merging and filtering tool for illumina paired-end reads for 16S rRNA amplicon sequencing.
    Author: Parikh HI, Koparde VN, Bradley SP, Buck GA, Sheth NU.
    Journal: BMC Bioinformatics; 2016 Dec 01; 17(1):491. PubMed ID: 27905885.
    Abstract:
    BACKGROUND: Recent advances in next-generation sequencing have revolutionized genomic research. 16S rRNA amplicon sequencing using paired-end sequencing on the MiSeq platform from Illumina, Inc., is being used to characterize the composition and dynamics of extremely complex/diverse microbial communities. For this analysis on the Illumina platform, merging and quality filtering of paired-end reads are essential first steps in data analysis to ensure the accuracy and reliability of downstream analysis. RESULTS: We have developed the Merging and Filtering Tool (MeFiT) to combine these pre-processing steps into one simple, intuitive pipeline. MeFiT invokes CASPER (context-aware scheme for paired-end reads) for merging paired-end reads and provides users the option to quality filter the reads using the traditional average Q-score metric or using a maximum expected error cut-off threshold. CONCLUSIONS: MeFiT provides an open-source solution that permits users to merge and filter paired end illumina reads. The tool has been implemented in python and the source-code is freely available at https://github.com/nisheth/MeFiT .
