        --manual   -m  when trying to guess the proper SO term, if more than
                       one option matches the primary tag, the converter will
                       wait for user input to choose the correct one

                       output file for each input file)
        --ethresh  -e  error threshold for unflattener
                       set this high (>2) to ignore all unflattener errors
        --[no]CDS  -c  Keep CDS-exons, or convert to alternate gene-RNA-protein-exon
                       model. --CDS is default. Use --CDS to keep default GFF gene model,
                       use --noCDS to convert to g-r-p-e.
        --format   -f  Input format (SeqIO types): GenBank, Swiss or Uniprot, EMBL work
                       (GenBank is default)
        --GFF_VERSION  3 is default, 2 and 2.5 and other Bio::Tools::GFF versions available

        --typesource   SO sequence type for source (e.g. chromosome; region; contig)
        --help     -h  display this message


=head1 DESCRIPTION

This script uses Bio::SeqFeature::Tools::Unflattener and
Bio::Tools::GFF to convert GenBank flatfiles to GFF3 with gene
containment hierarchies mapped for optimal display in gbrowse.

The input files are assumed to be gzipped GenBank flatfiles for refseq
contigs.  The files may contain multiple GenBank records.  Either a
single file or an entire directory can be processed.  By default, the
DNA sequence is embedded in the GFF but it can be saved into separate
fasta file with the --split(-y) option.

If an input file contains multiple records, the default behaviour is
to dump all GFF and sequence to a file of the same name (with .gff
appended).  Using the 'nolump' option will create a separate file for
each genbank record.  Using the 'split' option will create separate
GFF and Fasta files for each genbank record.


=head2 Notes

=head3 'split' and 'nolump' produce many files

In cases where the input files contain many GenBank records (for
example, the chromosome files for the mouse genome build), a very
large number of output files will be produced if the 'split' or
'nolump' options are selected.  If you do have lists of files E<gt> 6000,
use the --long_list option in bp_bulk_load_gff.pl or
bp_fast_load_gff.pl to load the gff and/ or fasta files.

=head3 Designed for RefSeq

This script is designed for RefSeq genomic sequence entries.  It may
work for third party annotations but this has not been tested.
But see below, Uniprot/Swissprot works, EMBL and possibly EMBL/Ensembl
if you don't mind some gene model unflattener errors (dgg).

=head3 G-R-P-E Gene Model

Don Gilbert worked this over with needs to produce GFF3 suited to
loading to GMOD Chado databases.  Most of the changes I believe are
suited for general use.  One main chado-specific addition is the
  --[no]cds2protein  flag

My favorite GFF is to set the above as ON by default (disable with --nocds2prot)
For general use it probably should be OFF, enabled with --cds2prot.

This writes GFF with an alternate, but useful Gene model,
instead of the consensus model for GFF3

  [ gene > mRNA> (exon,CDS,UTR) ]

This alternate is

  gene > mRNA > polypeptide > exon

means the only feature with dna bases is the exon.  The others
specify only location ranges on a genome.  Exon of course is a child
of mRNA and protein/peptide.

The protein/polypeptide feature is an important one, having all the
annotations of the GenBank CDS feature, protein ID, translation, GO
terms, Dbxrefs to other proteins.

UTRs, introns, CDS-exons are all inferred from the primary exon bases
inside/outside appropriate higher feature ranges.   Other special gene
model features remain the same.

Several other improvements and bugfixes, minor but useful are included

  * IO pipes now work:
    curl ftp://ncbigenomes/... | bp_genbank2gff3 --in stdin --out stdout | gff2chado ...

  * GenBank main record fields are added to source feature, e.g. organism, date,
    and the sourcetype, commonly chromosome for  genomes, is used.

  * Gene Model handling for ncRNA, pseudogenes are added.

  * GFF header is cleaner, more informative.
    --GFF_VERSION flag allows choice of v2 as well as default v3

  * GFF ##FASTA inclusion is improved, and
    CDS translation sequence is moved to FASTA records.

  * FT -> GFF attribute mapping is improved.

  * --format choice of SeqIO input formats (GenBank default).
    Uniprot/Swissprot and EMBL work and produce useful GFF.

  * SeqFeature::Tools::TypeMapper has a few FT -> SOFA additions
      and more flexible usage.

=head1 TODO

=head2 Are these additions desired?

 * filter input records by taxon (e.g. keep only organism=xxx or taxa level = classYYY
 * handle Entrezgene, other non-sequence SeqIO structures (really should change
    those parsers to produce consistent annotation tags).
