Hi Eric There is already a genbank format in the EMBOSS datatypes (although there is talk of defining this and others in a set of smaller repositories defined as its dependencies for more modularity). Note it uses "genbank" not "gb" as the name! https://toolshed.g2.bx.psu.edu/view/devteam/emboss_datatypes However that doesn't answer your question :( Peter On Mon, Jul 14, 2014 at 7:31 PM, Eric Rasche <rasche.eric@yandex.ru> wrote:

I'm trying to add a new datatype to my galaxy instance for genbank files, however I'm running into various issues. I've followed the tutorial (https://wiki.galaxyproject.org/Admin/Datatypes/Adding%20Datatypes)
however that example subclasses tabular, and I'd like to subclass Text as they're plain text files, and I'd like to be able to define a sniffer for them (not possible if your type=galaxy.datatypes.data:Text)
I figured the call ought to be something like
<datatype extension="gb" type="galaxy.datatypes.data:Genbank" subclass="True" />
however, everything I try fails with
Error importing datatype module galaxy.datatypes.data: 'module' object has no attribute 'Genbank'
To avoid this particular issue, I tried writing a separate datatype just for genbank files (type="galaxy.datatypes.genbank:Genbank"), however that fails with the same error:
galaxy.datatypes.registry ERROR 2014-07-14 13:23:23,100 Error importing datatype module galaxy.datatypes.genbank: 'module' object has no attribute 'genbank' Traceback (most recent call last): File "/home/hxr/work/galaxy-central/lib/galaxy/datatypes/registry.py", line 206, in load_datatypes module = getattr( module, mod ) AttributeError: 'module' object has no attribute 'genbank'
Here's my lib/galaxy/datatypes/genbank.py looks like:
import pkg_resources pkg_resources.require( "bx-python" ) import logging from galaxy.datatypes import data log = logging.getLogger(__name__)
class Genbank( data.Text ): file_ext = "gb"
def sniff( self, filename ): header = open(filename).read(5) return header == 'LOCUS'
To debug this, I've tried copying the tabular data type completely, removed all the classes other than Tabular, and renamed it "Genbank", however this fails too with the same error.
Can anyone offer some insight?
