jpayne@69: Description:  Aligns SSUs to each other and reports identity.
jpayne@69: This requires sequences annotated with a taxID in their header.
jpayne@69: 
jpayne@69: Usage:  comparessu.sh in=<input file> out=<output file>
jpayne@69: 
jpayne@69: Input may be fasta or fastq, compressed or uncompressed.
jpayne@69: 
jpayne@69: Standard parameters:
jpayne@69: in=<file>       Input sequences.
jpayne@69: out=<file>      Output data.
jpayne@69: t=              Set the number of threads; default is logical processors.
jpayne@69: overwrite=f     (ow) Set to false to force the program to abort rather than
jpayne@69:                 overwrite an existing file.
jpayne@69: showspeed=t     (ss) Set to 'f' to suppress display of processing speed.
jpayne@69: ziplevel=2      (zl) Set to 1 (lowest) through 9 (max) to change compression
jpayne@69:                 level; lower compression is faster.
jpayne@69: reads=-1        If positive, quit after this many sequences.
jpayne@69: 
jpayne@69: Processing parameters:
jpayne@69: ata=f           Do an all-to-all comparison.  Otherwise, each sequence will
jpayne@69:                 only be compared to one other randomly-selected sequence
jpayne@69:                 per taxonomic level.
jpayne@69: minlen=0        Ignore sequences shorter than this.
jpayne@69: maxlen=BIG      Ignore sequences longer than this.
jpayne@69: maxns=-1        If positive, ignore sequences with more than this many Ns.
jpayne@69: 
jpayne@69: 
jpayne@69: Java Parameters:
jpayne@69: -Xmx            This will set Java's memory usage, overriding autodetection.
jpayne@69:                 -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.
