Hi, Hans, Thanks for the link. I figured out the problem. It turned out the data type nexus was registered twice in the datatypes_conf.xml and the second one was not using the right type. THanks, Luobin On Fri, Jul 22, 2011 at 1:19 AM, Hans-Rudolf Hotz <hrh@fmi.ch> wrote:

Hi Luobin

It is difficult to guess without seeing your code.

So, assuming you followed the steps described in the wiki ( http://wiki.g2.bx.psu.edu/**Admin/Datatypes/Adding%**20Datatypes<http://wiki.g2.bx.psu.edu/Admin/Datatypes/Adding%20Datatypes>), I guess you just made a typo somewhere (since this has happen to me several times when adding a new datatype). Have you double checked your tool definition file?

Regards, Hans

Hi,

I created an XML file for a tool. This tool has an Nexus input. When I click the input field of the web interface for this tool, it shows all kinds of data that I can select. How do I restrict the list to show only data in nexus format? I added a line in the registration part and the sniffer part of the datatypes_conf.xml and I also created a class called Nexus which inherits the class galaxy.datatypes.Sequence, but this doesn't solve the problem.

Thanks, Luobin
