.SH DESCRIPTION

The program
.B 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.

.SH OPTIONS
.TP
\fB\-b\fR hash\-file
Build hash tables (hash\-file) from sequence files,
.TP
\fB\-T\fR hash\-file
Print word usage statistics for hash\-file
.TP
\fB\-o\fR outfile
Write output to file `outfile'

.SS "build-options:"
.TP
\fB\-w\fR wordsize
Set word size when building hash tables
.TP
\fB\-f\fR period
Set discontiguity when building hash tables
.TP
\fB\-k\fR
Skip repeats when building hash\-file
.TP
\fB\-F\fR min,max
Set watermarks for fragment size (in Mb) (version 1 only)
.TP
\fB\-c\fR cachesize
Set cache size (version 2 only)
.TP
\fB\-v\fR ver
Use format version (1|2, 2 is default)
