Description:  Makes vectors for QuickBin network training.

Usage: makequickbinvector.sh in=contigs.fa out=vector.txt cov=cov.txt lines=1m

Parameters:
in=<file>       Assembly input; only required parameter.
cov=<file>      Cov file generated by Quickbin from sam files.
out=<file>      Output file.
lines=1m        Lines to output.
rate=0.5        Fraction of vectors with positive results.
mincontig=200   Do not load contigs shorter than this.
minlen=0        Do not print comparisons where either contig is shorter 
                than this.
maxlen=2B       Do not print comparisons where both contigs are longer
                than this.
maxgcdif=1.0    Max allowed GC difference for output.
maxkmerdif=1.0  Max allowed TNF cosine difference for output.
mcc=9           Max contigs per cluster.
maxdepthratio=1000.0  Max allowed depth ratio for output.

Java Parameters:
-Xmx            This will set Java's memory usage, overriding autodetection.
                -Xmx20g will specify 20 gigs of RAM, and -Xmx200m will
                specify 200 megs. The max is typically 85% of physical memory.
-eoom           This flag will cause the process to exit if an out-of-memory
                exception occurs.  Requires Java 8u92+.
-da             Disable assertions.
