jpayne@69: Description:  Shrinks accession2taxid tables by removing unneeded columns.
jpayne@69: This is not necessary but makes accession2taxid files smaller and load faster.
jpayne@69: 
jpayne@69: Usage:  shrinkaccession.sh in=<file> out=<outfile>
jpayne@69: 
jpayne@69: Parameters:
jpayne@69: ow=f            (overwrite) Overwrites files that already exist.
jpayne@69: app=f           (append) Append to files that already exist.
jpayne@69: zl=4            (ziplevel) Set compression level, 1 (low) to 9 (max).
jpayne@69: pigz=t          Use pigz for compression, if available.
jpayne@69: gi=t            Retain gi numbers.
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 specify 200 megs.
jpayne@69:                     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+.
