DB2quiva [-vU] path:db
The set of .quiva files within the given DB are recreated from the DB exactly as they were input. That is, this is a perfect inversion, including the reconstitution of the proper .quiva headers. Because of this property, one can, if desired, delete the .quiva source files once they are in the DB as they can always be recreated from it. By .fastq convention each QV vector is output as a line without new-lines, and by default the Deletion Tag entry is in lower case letters. The -U option specifies upper case letters should be used instead.
