Hi David,

Am happy to generate some pepXMLs from the tutorial data, but assuming you 
mean the stuff at:

ftp://ftp.peptideatlas.org/pub/PeptideAtlas/Repository/TPP_Demo2009/

... I'm not sure that's the best to work with for Morpheus. It's CID 
Ion-trap MS/MS, which is not Morpheus' target. Morpheus doesn't work as 
well as other algorithms on low-res MS/MS so I'm not sure if anyone would 
want to use it like that.

I grabbed two of the result sets from the Coon lab site - Yeast analysis 
with FT HCD or IT CID. The distributions of Morpheus scores are very 
different. The CID data doesn't even look like target and decoy matches are 
separable, so I think high-res MS/MS is a must. See attached.

DT
