NAME

       fahash - sequence hash builder for reverse e-PCR

SYNOPSIS

       fahash [-hV] -b hash-file [-w wdsize] [-f period] [-F fragment_min,fragment_max] [-k] [-c cachesize] [-v 1|2] famap-file ...

       fahash [-hV] -T hash-file [-o outfile]

DESCRIPTION

       The program fahash is part of the e-PCR suite and is used to build hash-files, and output word usage statistics for reverse e-PCR searches.

OPTIONS

       -b hash-file
	      Build hash tables (hash-file) from sequence files,

       -T hash-file
	      Print word usage statistics for hash-file

       -o outfile
	      Write output to file `outfile'

   build-options:
       -w wordsize
	      Set word size when building hash tables

       -f period
	      Set discontiguity when building hash tables

       -k     Skip repeats when building hash-file

       -F min,max
	      Set watermarks for fragment size (in Mb) (version 1 only)

       -c cachesize
	      Set cache size (version 2 only)

       -v ver Use format version (1|2, 2 is default)

EXAMPLE

	famap -tN -b genome.famap org/chr_*.fa

	fahash -b genome.hash -w 12 -f3 ${PWD}/genome.famap

	re-PCR -s genome.hash -n1 -g1 ACTATTGATGATGA AGGTAGATGTTTTT 120-200
