Description:  Compares query sketches to reference sketches hosted on a 
remote server via the Internet.  The input can be sketches made by sketch.sh,
or fasta/fastq files from which SendSketch will generate sketches.  
Only sketches will sent, not sequences.

Please read bbmap/docs/guides/BBSketchGuide.txt for more information.

Usage:  
sendsketch.sh in=file

To change nucleotide servers, add the server name, e.g.:
sendsketch.sh in=file nt

For the protein server with nucleotide input:
sendsketch.sh in=file protein

for the protein server with amino input:
sendsketch.sh in=file amino protein


Standard parameters:
in=<file>       Sketch or fasta file to compare.
out=stdout      Comparison output.  Can be set to a file instead.
outsketch=      Optional, to write the sketch to a file.
local=f         For local files, have the server load the sketches.
                Allows use of whitelists; recommended for Silva.
                Local can only be used when the client and server access 
                the same filesystem - e.g., Genepool and Cori.
address=        Address of remote server.  Default address:
                https://refseq-sketch.jgi-psf.org/sketch
                You can also specify these abbreviations:
                   nt:      nt server
                   refseq:  Refseq server
                   silva:   Silva server
                   protein: RefSeq prokaryotic amino acid sketches
                   img:     IMG server (Not Yet Available)
                   mito:    RefSeq mitochondrial server (NYA)
                   fungi:   RefSeq fungi sketches (NYA)
                Using an abbreviation automatically sets the address, 
                the blacklist, and k.

Sketch-making parameters:
mode=single     Possible modes, for fasta input:
                   single: Generate one sketch per file.
                   sequence: Generate one sketch per sequence.
k=31            Kmer length, 1-32.  This is automatic and does not need to
                be set for JGI servers, only for locally-hosted servers.
samplerate=1    Set to a lower value to sample a fraction of input reads.
                For raw reads (rather than an assembly), 1-3x coverage
                gives best results, by reducing error kmers.  Somewhat
                higher is better for high-error-rate data like PacBio.
minkeycount=1   Ignore kmers that occur fewer times than this.  Values
                over 1 can be used with raw reads to avoid error kmers.
minprob=0.0001  Ignore kmers below this probability of correctness.
minqual=0       Ignore kmers spanning bases below this quality.
entropy=0.66    Ignore sequence with entropy below this value.
merge=f         Merge paired reads prior to sketching.
amino=f         Use amino acid mode.  Input should be amino acids.
translate=f     Call genes and translate to proteins.  Input should be
                nucleotides.  Designed for prokaryotes.
sixframes=f     Translate all 6 frames instead of predicting genes.
ssu=t           Scan for and retain full-length SSU sequence.

Size parameters:
size=10000      Desired size of sketches (if not using autosize).
mgf=0.01        (maxfraction) Max fraction of genomic kmers to use.
minsize=100     Do not generate sketches for genomes smaller than this.
autosize=t      Use flexible sizing instead of fixed-length.  This is
                nonlinear; a human sketch is only ~6x a bacterial sketch.
sizemult=1      Multiply the autosized size of sketches by this factor.
                Normally a bacterial-size genome will get a sketch size
                of around 10000; if autosizefactor=2, it would be ~20000.
density=        If this flag is set (to a number between 0 and 1),
                autosize and sizemult are ignored, and this fraction of
                genomic kmers are used.  For example, at density=0.001,
                a 4.5Mbp bacteria will get a 4500-kmer sketch.
sketchheapfactor=4  If minkeycount>1, temporarily track this many kmers until
                counts are known and low-count kmers are discarded.

Taxonomy and filtering parameters:
level=2         Only report the best record per taxa at this level.
                Either level names or numbers may be used.

                   ...etc
include=        Restrict output to organisms in these clades.
                May be a comma-delimited list of names or NCBI TaxIDs.
includelevel=0  Promote the include list to this taxonomic level.
                For example, include=h.sapiens includelevel=phylum

includestring=  Only report records whose name contains this string.
exclude=        Ignore organisms in these clades.
                May be a comma-delimited list of names or NCBI TaxIDs.
excludelevel=0  Promote the exclude list to this taxonomic level.
                For example, exclude=h.sapiens excludelevel=phylum
                would exclude all organisms in the same phylum as human.
excludestring=  Do not records whose name contains this string.
banunclassified=f   Ignore organisms descending from nodes like 
                    'unclassified Bacteria'

                   and sizeRatio.

                into calculations.  Kmers are considered contaminant if
                present in some ref sketch but not the current one.
printunique=t   Number of matches unique to this reference.
printunique2=f  Number of matches unique to this reference's taxa.

NOTE: unique2/unique3/contam2/refhits require an index.

printdepth=f    (depth) Print average depth of sketch kmers; intended
                for shotgun read input.
printdepth2=f   (depth2) Print depth compensating for genomic repeats.
                Requires reference sketches to be generated with depth.
actualdepth=t   If this is false, the raw average count is printed.

                to estimated actual depth (including uncovered areas).

Sorting:
sortbyscore=t   Default sort order is by score.

sortbyvolume=f  Include volume as a factor in sort order.
sortbykid=f     Sort strictly by KID.

                this fraction of the size of the larger.
records=20      Report at most this many best-matching records.
color=family    Color records at the family level.  color=f will disable.
                Colors work in most terminals but may cause odd characters
                to appear in text editors.  So, color defaults to f if 
                writing to a file.
intersect=f     Print sketch intersections.  delta=f is suggested.

Metadata parameters (optional, for the query sketch header):
taxid=-1        Set the NCBI taxid.
imgid=-1        Set the IMG id.
spid=-1         Set the sequencing project id (JGI-specific).
name=           Set the name (taxname).
name0=          Set name0 (normally the first sequence header).
fname=          Set fname (normally the file name).
meta_=          Set an arbitrary metadata field.
                For example, meta_Month=March.

Other parameters:
requiredmeta=   (rmeta) Required optional metadata values.  For example:
                rmeta=subunit:ssu,source:silva
bannedmeta=     (bmeta) Forbidden optional metadata values.

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.
