PROGRAM:

NAME

DBsplit - divide a Dazzler database into a series of blocks

SYNOPSIS

DBsplit [-a] [-xint] [-sint(200)] path:db|dam

DESCRIPTION

Divide the database path.db or path.dam conceptually into a series of blocks referable to
on the command line as path.1, path.2, ... If the -x option is set then all reads less
than the given length are ignored, and if the -a option is not set then secondary reads
from a given well are also ignored. The remaining reads, constituting what we call the
trimmed DB, are split amongst the blocks so that each block is of size -s * 1Mbp except
for the last which necessarily contains a smaller residual. The default value for -s is
200Mbp because blocks of this size can be compared by our "overlapper" daligner(1) in
roughly 16Gb of memory. The blocks are very space efficient in that their sub-index of
the master .idx is computed on the fly when loaded, and the .bps and .qvs files (if a .db)
of base pairs and quality values, respectively, is shared with the master DB. Any
relevant portions of tracks associated with the DB are also computed on the fly when
loading a database block.
