Snagger (software)
Snagger is a bioinformatics software program for selecting tag SNPs using pairwise r2 linkage disequilibrium.[1] It is implemented as extension to the popular software, Haploview, and is freely available under the MIT License.[2] Snagger distinguishes itself from existing single nucleotide polymorphism (SNP) selection algorithms, including Tagger,[3] by providing user options that allow for:
- Prioritization of tagSNPs based on certain characteristics, including platform-specific design scores, functionality (i.e. coding status), and chromosomal position
- Efficient selection of SNPs across multiple populations
- Selection of tagSNPs outside defined genomic regions to improve coverage and genotyping success
- Picking of surrogate tagSNPs that serve as backups for tagSNPs whose failure would result in a significant loss of data
Haploview with Snagger has been developed and is maintained at the Genomics Center at the University of Southern California.
