I'm having a problem displaying NEXUS files in Galaxy's Phyloviz viewer.  Any help would be greatly appreciated. When I try and view the simple nexus file I get the error below:

Hello,

This error indicates that an expected line of the input was not found during the tool execution. Input format is generally the first place to look for the root cause. If you modify the format of the input to be exactly within specification (and assign the datatype, if you have not done this already) does it help?

For example, change the header from: 

#NEXUS
[R-package APE, Mon Oct 27 17:31:54 2014]

BEGIN TAXA;

To be:

#NEXUS
BEGIN TAXA;

You can do this before upload, or by using a combination of dataset line selection tools in the tool group "Text Manipulation".

This is a bit of a laundry list of ways to correct inputs/errors, but it may be helpful.
http://wiki.galaxyproject.org/Support#Error_from_tools

It is how I begin troubleshooting. Please note that all datatypes are not in the wiki 'Datatypes' link, just the most commonly used. But this is a wiki, please feel free to edit and add it in! To see all defined datatypes within Galaxy: click on the pencil icon for a dataset, then in the center panel go into the tab "Datatype" to search. If a datatype is listed here, it available on the instance you are working on. Nexus is defined on the public Main Galaxy instance at http://usegalaxy.org

Please let us know if this resolves the issue or not, Jen, Galaxy team

I tried deleting the extra line as you suggested, but I still get the same error. I'm kind of at a loss to figuring out why it doesn't work. I've tried opening this in other viewers and it accepts them. Any additional help would be greatly appreciated
