NAME

       bamfilterheader - filter auxiliary tags from BAM file

SYNOPSIS

       bamfilterheader [options]

DESCRIPTION

       bamfilterheader  reads a BAM file from a file, filters the header and writes the resulting
       data to standard output as a BAM file. Filtering the header consists of removing  sequence
       (SQ)  lines and read group (RG) lines which are not referenced in any alignment. The input
       file is scanned twice during the process, so the name  of  the  input  file  needs  to  be
       provided using the I key.

       The  following  key=value  pairs can be given, where the keep and remove keys are mutually
       exclusive.

       I=<inputfilename>: name of input BAM file

       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.
