jpayne@69: Description:  Fuses sequences together, padding gaps with Ns.
jpayne@69: 
jpayne@69: Usage:   fuse.sh in=<input file> out=<output file> pad=<number of Ns>
jpayne@69: 
jpayne@69: Parameters:
jpayne@69: in=<file>       The 'in=' flag is needed if the input file is not the 
jpayne@69:                 first parameter.  'in=stdin' will pipe from standard in.
jpayne@69: out=<file>      The 'out=' flag is needed if the output file is not the 
jpayne@69:                 second parameter.  'out=stdout' will pipe to standard out.
jpayne@69: pad=300         Pad this many N between sequences.
jpayne@69: maxlen=2g       If positive, don't make fused sequences longer than this.
jpayne@69: quality=30      Fake quality scores, if generating fastq from fasta.
jpayne@69: overwrite=t     (ow) Set to false to force the program to abort rather 
jpayne@69:                 than overwrite an existing file.
jpayne@69: ziplevel=2      (zl) Set to 1 (lowest) through 9 (max) to change 
jpayne@69:                 compression level; lower compression is faster.
jpayne@69: fusepairs=f     Default mode fuses all sequences into one long sequence.
jpayne@69:                 Setting fusepairs=t will instead fuse each pair together.
jpayne@69: name=           Set name of output sequence.  Default is the name of
jpayne@69:                 the first input sequence.
jpayne@69: 
jpayne@69: Java Parameters:
jpayne@69: -Xmx            This will set Java's memory usage, overriding
jpayne@69:                 autodetection.  -Xmx20g will specify 20 gigs of RAM, and -Xmx200m will
jpayne@69:                 specify 200 megs. The max is typically 85% of physical memory.
jpayne@69: -eoom           This flag will cause the process to exit if an out-of-memory
jpayne@69:                 exception occurs.  Requires Java 8u92+.
jpayne@69: -da             Disable assertions.
