Editing bam header
WebLearning the BAM format Introduction. SAMtools provides various (sub)tools for manipulating alignments in the SAM/BAM format. The SAM (Sequence Alignment/Map) format (BAM is just the binary form of SAM) is currently the de facto standard for storing large nucleotide sequence alignments. If you are working with high-throughput … WebSep 20, 2024 · The header and alignment section are internally consistent: each aligned read has an RNAME (reference sequence name, 3 rd field) that matches an SN tag value from the header (e.g., CHROMOSOME_I), and, if provided, the alignment read group optional field (RG:Z:) is consistent with the read group ID in the header (1).It is also …

WebFastQ Format. The official documentation for FastQ format can be found here. This is the most widely used format in sequence analysis as well as what is generally delivered from a sequencer. Many analysis tools require this format because it contains much more information than FastA. The format is similar to fasta though there are differences ... WebBAM Format. This is the same format except that it encoded in binary which means that it is significantly smaller than the SAM files and significantly faster to read, though it is not human legible and needs to …
WebBefore you are able to use the BAM files you will need to edit them to make the RG ID unique, for instance by adding the SM name to the RG ID. ... you will need to modify the BAM header to include/modify the missing/incorrect fields, for which you can use the samtools reheader functionality. http://quinlanlab.org/tutorials/samtools/samtools.html
WebNov 20, 2013 · To convert SAM to BAM, we use the samtools view command. We must specify that our input is in SAM format (by default it expects BAM) using the -S option. We must also say that we want the output to be BAM (by default it produces BAM) with the -b option.

WebBAM files use the file naming format of SampleName_S#.bam, where # is the sample number determined by the order that samples are listed for the run. In multi-node mode, the S# is set to S1, regardless the order of the sample.
