NAME

       dexqv - compress a set of .quiva files

SYNOPSIS

       dexqv [-vkl] <path:quiva> ...

DESCRIPTION

       Dexqv  compresses  a  set  of  .quiva  files  into new files with a .dexqv extension. That is, submitting
       G.quiva will result in a compressed image G.dexqv, and G.quiva will not longer exist.

       The -k flag prevents the removal of G.quiva. With -v set progress is reported, otherwise the command runs
       silently. If slightly more compression is desired at the expense of being a bit "lossy" then set  the  -l
       option.  This  option is experimental in that it remains to be seen if Quiver gives the same results with
       the scaled values responsible for the loss. Undexqv reverses the  compression  of  dexqv,  replacing  the
       uncompressed  image  of  G.dexqv  with  G.quiva. The flags are analgous to the v & k flags for dexqv. The
       compression factor is typically 3.4 or so (4.0 or so with -l set).

       By .fastq convention each QV vector is output by undexqv as a line without intervening new-lines, and  by
       default  the  Deletion  Tag  vector  is in lower case letters. The -U option specifies upper case letters
       should instead be used for said vector.
