Generating the dax and then looking into it, I see:

$ fgrep '"out"' X.dax
<stdout name="CARDIA-Lipids_Paper006T3snp-2010-10-11.html" link="out" />
<stdout name="CARDIA-Lipids_Paper006T3pheno-2010-10-11.html" link="out" />
<stdout name="CARDIA-Lipids_Paper006T3assoc-2010-10-11.html" link="out" />
<stderr name="CARDIA-Lipids_Paper006T3snp-2010-10-11.canon.log" link="out" />
<stderr name="CARDIA-Lipids_Paper006T3pheno-2010-10-11.canon.log" link="out" />
<stderr name="CARDIA-Lipids_Paper006T3assoc-2010-10-11.canon.log" link="out" />
<stderr name="property_rewrite.log" link="out" />
<stdout name="data_upload.out" link="out" />
<stderr name="data_upload.log" link="out" />

This is wrong by the schema, and should be "output".
