Hi, <div><br></div><div>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&#39;t solve the problem.</div>
<div><br></div><div>Thanks,</div><div>Luobin </div>
