Hi, As you probably already know, the MG-RAST job (13910, cladeIA_454reads2) was created from a '._' (._GBZF.GSIO.fna) file which Mac OS X includes with a tar file and does not contain sequence data. I am going to delete it as it an artifact of the system. -- Regards, Mark D'Souza -- for the MG-RAST team [email protected] http://metagenomics.anl.gov/ If you need to respond to this email please address it to the mailing-list [email protected]
