[Bioperl-l] bp_pg_bulk_load_gff.pl: invalid command \N

[Scott Cain]

Hi Jan,

What version of Postgres are you using?  At some point, the bulk loading
format for Postgres changed, and bp_pg_bulk_load_gff.pl only supports
the newer format.  I believe that this change occurred between
7.2->7.3.  If you are using an older Postgres, you should be able to
still use bp_load_gff.pl, though it will be slower.

Hi all,

Has anyone encountered the following errors when trying to load a gff
file into a PostgresQL database? The bioperl version is 1.4. The gff
file looks like this:

[start gff file]
GGA10_random    Blast   Gene    1906433 1908278 1e-102  +       .      
Gene VIM ; Accession NM_003380.1
GGA10_random    Blast   Gene    1539573 1542536 0.0     +       .      
Gene GTF2E1 ; Accession NM_005513.1
[stop gff file]

Any help appreciated.
