.SH "NAME"
$0 \- Prepares a GFF3 file for bulk loading into a chado database.

.Vb 1

.Ve
.SH "COMMAND-LINE OPTIONS"
.IX Header "COMMAND-LINE OPTIONS"
.Vb 12
\& \-\-gfffile        The file containing GFF3 (optional, can read
\&                     from stdin)
\& \-\-outfile        The name kernel that will be used for naming result files
\& \-\-splitfile      Split the files into more manageable chunks, providing
\&                     an argument to control splitting
\& \-\-onlysplit      Split the files and then quit (ie, don\*(Aqt sort)
\& \-\-nosplit        Don\*(Aqt split the files (ie, only sort)
\& \-\-hasrefseq      Set this if the file contains a reference sequence line
\&                     (Only needed if not splitting files)
\& \-\-dbprofile      Specify a gmod.conf profile name (otherwise use default)
\& \-\-inheritance_tiers How many levels of inheritance do you expect tis file
\&                     to have (default: 3)
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
splitfile  \*(-- Just setting this flag to 1 will cause the file to be split 
by reference sequence.  If you provide an optional argument, it will be
further split according to these rules:
.PP
.Vb 5
\& source=1     Splits files according to the value in the source column
\& source=a,b,c Puts lines with sources that match (via regular expression)
\&                     \*(Aqa\*(Aq, \*(Aqb\*(Aq, or \*(Aqc\*(Aq in a separate file
\& type=a,b,c   Puts lines with types that match \*(Aqa\*(Aq, \*(Aqb\*(Aq, or \*(Aqc\*(Aq in a
\&                     separate file
.Ve
.PP
For example, if you wanted all of your analysis results to go in a separate
file, you could indicate '\-\-splitfile type=match', and all cDNA_match,
EST_match and cross_genome_match features would go into separate files
(separate by reference sequence).
.PP
inheritence_tiers \*(-- The number of levels of inheritance this file has. 
For example, if the file has \*(L"central dogma\*(R" genes in it (gene/mRNA/
exon,polypeptide), then it has 3.  Up to 4 is supported but the higher
the number, the more slowly it performs.  If you don't know, 3 is a 
reasonable guess.
.SS "\s-1FASTA\s0 sequence"
.IX Subsection "FASTA sequence"
If the \s-1GFF3\s0 file contains \s-1FASTA\s0 sequence at the end, the sequence
will be placed in a separate file with the extension '.fasta'.  This
fasta file can be loaded separately after the split and/or sorted
\&\s-1GFF3\s0 files are loaded, using the command:
.PP
.Vb 1
\&  gmod_bulk_load_gff3.pl \-g <fasta file name>
