Description:  Concatenates barcodes and quality onto read names.

Usage:        mergebarcodes.sh in=<file> out=<file> barcode=<file>

Input may be stdin or a fasta or fastq file, raw or gzipped.
If you pipe via stdin/stdout, please include the file type; e.g. for gzipped fasta input, set in=stdin.fa.gz


Optional parameters (and their defaults)

Input parameters:
in=<file>           Input reads. 'in=stdin.fq' will pipe from standard in.
bar=<file>          File containing barcodes.
interleaved=auto    (int) If true, forces fastq input to be paired and interleaved.
qin=auto            ASCII offset for input quality.  May be 33 (Sanger), 64 (Illumina), or auto.

Output parameters:
out=<file>          Write muxed sequences here.  'out=stdout.fa' will pipe to standard out.
overwrite=t         (ow) Set to false to force the program to abort rather than overwrite an existing file.
ziplevel=2          (zl) Set to 1 (lowest) through 9 (max) to change compression level; lower compression is faster.
qout=auto           ASCII offset for output quality.  May be 33 (Sanger), 64 (Illumina), or auto (same as input).

Other parameters:
pigz=t              Use pigz to compress.  If argument is a number, that will set the number of pigz threads.
unpigz=t            Use pigz to decompress.

Java Parameters:
-Xmx                This will be passed to Java to set memory usage, overriding the program's automatic memory detection.
                    -Xmx20g will specify 20 gigs of RAM, and -Xmx200m will specify 200 megs.  The max is typically 85% of physical memory.
