NAME

       bamrecalculatecigar - concatenate BAM files

SYNOPSIS

       bamrecalculatecigar [options]

DESCRIPTION

       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.
