The output can be easily imported into a genome viewer, such as SeqMonk, and enables a researcher to analyse the methylation levels of their samples straight away. It's main features are: + + - Bisulfite mapping and methylation calling in one single step + + - Supports single-end and paired-end read alignments + + - Supports ungapped and gapped alignments + + - Alignment seed length, number of mismatches etc. are adjustable + + - Output discriminates between cytosine methylation in CpG, CHG and CHH context + +.. _Bismark: http://www.bioinformatics.babraham.ac.uk/projects/bismark/ + +**Input formats** + +Bismark accepts files in Sanger FASTQ format. + +**Outputs** + +The output is in SAM format, and has the following columns:: + + Column Description + -------- -------------------------------------------------------- + 1 QNAME seq-ID + 2 FLAG this flag tries to take the strand a bisulfite read originated from into account (this is different from ordinary DNA alignment flags!) + 3 RNAME chromosome + 4 POS start position + 5 MAPQ always 255 + 6 CIGAR + 7 RNEXT + 8 PNEXT + 9 TLEN + 10 SEQ + 11 QUAL Phred33 scale + 12 NM-tag edit distance to the reference + 13 XX-tag base-by-base mismatches to the reference, not including indels + 14 XM-tag methylation call string + 15 XR-tag read conversion state for the alignment + 16 XG-tag genome conversion state for the alignment + + + +
