bamrecalculatecigar - concatenate BAM files
bamrecalculatecigar [options]
bamrecalculatecigar reads a SAM/BAM/CRAM file, rewrites the CIGAR strings of
aligned reads replacing M operations by = and X operations and writes the
resulting data to a SAM/BAM/CRAM file. Unaligned reads are not changed.
Rewriting the CIGAR strings requires a reference in FastA format. The path to
this FastA file needs to be provided using the reference key. The alignment
input file needs to be sorted by coordinate.
The following key=value pairs can be given:
level=<-1|0|1|9|11>: set compression level of the output BAM file.
Valid values are
- -1:
- zlib/gzip default compression level
- 0:
- uncompressed
- 1:
- zlib/gzip level 1 (fast) compression
- 9:
- zlib/gzip level 9 (best) compression
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
- 11:
- igzip compression
verbose=<1>: Valid values are
- 1:
- print progress report on standard error
- 0:
- do not print progress report
tmpfile=<filename>: prefix for temporary files. By default the
temporary files are created in the current directory
md5=<0|1>: md5 checksum creation for output file. Valid values are
- 0:
- do not compute checksum. This is the default.
- 1:
- compute checksum. If the md5filename key is set, then the
checksum is written to the given file. If md5filename is unset, then no
checksum will be computed.
md5filename file name for md5 checksum if md5=1.
index=<0|1>: compute BAM index for output file. Valid values are
- 0:
- do not compute BAM index. This is the default.
- 1:
- compute BAM index. If the indexfilename key is set, then
the BAM index is written to the given file. If indexfilename is unset,
then no BAM index will be computed.
indexfilename file name for BAM index if index=1.
inputformat=<bam>: input file format. All versions of bamsort 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:
- bam:
- BAM (see http://samtools.sourceforge.net/SAM1.pdf)
- sam:
- SAM (see http://samtools.sourceforge.net/SAM1.pdf)
- cram:
- CRAM (see http://www.ebi.ac.uk/ena/about/cram_toolkit)
outputformat=<bam>: output file format. All versions of bamsort
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:
- bam:
- BAM (see http://samtools.sourceforge.net/SAM1.pdf)
- sam:
- SAM (see http://samtools.sourceforge.net/SAM1.pdf)
- cram:
- CRAM (see http://www.ebi.ac.uk/ena/about/cram_toolkit).
This format is not advisable for data sorted by query name.
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.
