BIOBAMBAM                                         January 2014                                BAMFILTERHEADER(1)

       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.
