GigaScience Database. RIS BibTeX Text

DNA methylation plays important roles in regulating gene expression and cellular specification. Reduced representation bisulfite sequencing (RRBS) has become prevailing in methylation studies due to its cost-effectiveness and single-base resolution. The rapid accumulation of RRBS data demands ingeniously and practically designed analytical tools. To streamline the data processing of DNA methylation in multiple RRBS samples, we present a flexible pipeline named SMAP, whose features include: 1) it handles single- and/or paired-end (SE/PE) diverse bisulfite sequencing data with reduced false positive rate in differentially methylated regions; 2) it detects allele-specific methylation events with improved algorithm; 3) it has a build-in pipeline for novel single nucleotide polymorphisms (SNP) detection; 4) it supports user-defined multiple restriction enzymes; 5) it basically conducts a one-step operation in all methylation analyses. SMAP is a modular pipeline implemented in Perl that calls software components written in C/C++, Perl, R and Java. Required input files for SMAP include BS or RRBS data in FASTQ format and a user-defined configuration file including all settings of the pipeline
