%prog htg fastafile template.sbt
Prepare sqnfiles for Genbank HTG submission to update existing records.
`fastafile` contains the records to update, multiple records are allowed
(with each one generating separate sqn file in the sqn/ folder). The record
defline has the accession ID. For example,
>AC148290.3
Internally, this generates two additional files (phasefile and namesfile)
and download records from Genbank. Below is implementation details:
`phasefile` contains, for each accession, phase information. For example:
AC148290.3 3 HTG 2 mth2-45h12
which means this is a Phase-3 BAC. Record with only a single contig will be
labeled as Phase-3 regardless of the info in the `phasefile`. Template file
is the Genbank sbt template. See jcvi.formats.sbt for generation of such
files.
Another problem is that Genbank requires the name of the sequence to stay
the same when updating and will kick back with a table of name conflicts.
For example:
We are unable to process the updates for these entries
for the following reason:
Seqname has changed
Accession Old seq_name New seq_name
--------- ------------ ------------
AC239792 mtg2_29457 AC239792.1
To prepare a submission, this script downloads genbank and asn.1 format,
and generate the phase file and the names file (use formats.agp.phase() and
apps.gbsubmit.asn(), respectively). These get automatically run.
However, use --phases if the genbank files contain outdated information.
For example, the clone name changes or phase upgrades. In this case, run
formats.agp.phase() manually, modify the phasefile and use --phases to override.
