bamstreamingmarkduplicates - mark duplicate reads
bamstreamingmarkduplicates [options]
bamstreamingmarkduplicates reads a coordinate sorted BAM, SAM or CRAM file, which has been previously processed by bamsort using the options fixmates=1 and adddupmarksupport=1, marks duplicate read pairs and reads and writes the resulting file in BAM, SAM or CRAM format. The preprocessing of the file using bamsort with the stated options is mandatory, i.e. bamstreamingmarkduplicates will fail without it. In contrast to bammarkduplicates and bammarkduplicates2 the streaming variant bamstreamingmarkduplicates processes the file in a single pass. bamstreamingmarkduplicates cannot handle files containing orphan pair ends (pairs where one of the two ends is missing in the file).
The following key=value pairs can be given:
M=<>: file name for metrics data. By default the metrics data is written on the standard error channel.
level=<-1|0|1|9|11>: set compression level of the output BAM file. Valid values are
If libmaus has been compiled with support for igzip (see https://software.intel.com/en-us/articles/igzip-a-high-performance-deflate-compressor-with-optimizations-for-genomic-data) then an additional valid value is
verbose=<1>: Valid values are
tmpfile=<filename>: set the prefix for temporary file names
disablevalidation=<0|1>: sets whether input validation is performed. Valid values are
md5=<0|1>: md5 checksum creation for output file. This option can only be given if outputformat=bam. Then valid values are
md5filename file name for md5 checksum if md5=1.
index=<0|1>: compute BAM index for output file. This option can only be given if outputformat=bam. Then valid values are
indexfilename file name for output BAM index if index=1.
inputformat=<bam>: input file format. All versions of bamstreamingmarkduplicates come with support for the BAM input format. If the program in addition is linked to the io_lib package, then the following options are valid:
outputformat=<bam>: output file format. All versions of bamstreamingmarkduplicates come with support for the BAM output format. If the program in addition is linked to the io_lib package, then the following options are valid:
I=<[stdin]>: input filename, standard input if unset.
O=<[stdout]>: output filename, standard output if unset.
inputthreads=<[1]>: input helper threads, only valid for inputformat=bam.
outputthreads=<[1]>: output helper threads, only valid for outputformat=bam.
reference=<[]>: reference FastA file for inputformat=cram and outputformat=cram. An index file (.fai) is required.
tag=<tag> name of auxiliary field storing tag information in string form. Read fragments or pairs with different tags will not be considered as duplicates, even they would be according to their mapping coordinates. For pairs the tag field information of the first and second mate are concatenated to obtain the tag of the pair.
nucltag=<tag> this option works like the tag option but is restricted to sequences of nucleotides (A,C,G or T) as tags. The length of each tag sequence is not allowed to exceed 15 bases. All tags are required to have the same length. Each non nucleotide symbol is mapped to A. In contrast to the tag option, nucltag uses less memory for processing and can be expected to be faster.
filterdupmarktags=<[0]>: remove the auxiliary fields MC, MQ, MS, and MT used for streaming duplicate marking when producing the output file. By default the fields are not removed.
