Hi Calvin, The "extension" is really the Galaxy datatype name, so put "quikrdb" here. The actual filename on disk will be *.dat once loaded into Galaxy. More examples, e.g. https://github.com/peterjc/galaxy_blast/blob/master/datatypes/blast_datatype... Peter On Fri, Sep 12, 2014 at 9:40 PM, Calvin Morrison <mutantturkey@gmail.com> wrote:

Hi,

I just want a simple data type for my 'custom' datatype (it's just a trained matrix in a specific format generated by my database building tool), so that my tools which use this database will only see ones with that format in the dropdown select list.

in my datatypes.xml i have this:

<datatype extension="gz" type="galaxy.datatypes.quikrdb" mimetype="application/octet-stream" display_in_upload="true" description="A database trained with quikr." />

then in my tool xml files i have

<outputs> <data name="output" format="quikrdb" /> </outputs>

which seems to be fine, but my tools which use it still show me all my data, not just trained db's

<param name="dbname" type="data" format="quikrdb" label="custom trained database"/>

Am i doing something wrong?
