Description:  Renames fasta sequences to indicate their NCBI taxIDs.
The headers must be in NCBI or Silva format with gi numbers,
accessions, or organism names.  Only supports fasta sequence files.

Usage:  gi2taxid.sh in=<file> out=<file> server

Parameters:
in=<file>       Input sequences; required parameter.  Must be fasta.
                This can alternatively be a comma-delimited list,
                or just a bunch of space-delimited filenames, e.g.:
                gi2taxid.sh x.fa y.fa z.fa out=tid.fa tree=auto table=auto
out=<file>      Destination for renamed sequences.
invalid=<file>  Destination for headers with no taxid.
keepall=t       Keep sequences with no taxid in normal output.
prefix=t        Append the taxid as a prefix to the old header, but keep
                the old header.
title=tid       Set the title of the new number (e.g. ncbi, taxid, tid).
ziplevel=2      (zl) Compression level for gzip output.
pigz=t          Spawn a pigz (parallel gzip) process for faster 
                compression than Java.  Requires pigz to be installed.
silva=f         Parse headers in Silva format.
shrinknames=f   Replace multiple concatenated headers with the first.

Taxonomy file flags:
server=f        Use the taxonomy server instead of local files.
                Server mode only works for accessions (like RefSeq).
tree=           Specify a taxtree file.  On Genepool, use 'auto'.
gi=             Specify a gitable file.  On Genepool, use 'auto'.
accession=      Specify one or more comma-delimited NCBI accession to
                taxid files.  On Genepool, use 'auto'.

Java Parameters:
-Xmx            This will set Java's memory usage, overriding autodetection.
                -Xmx20g will specify 20 gigs of RAM, and -Xmx800m will specify 800 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.
