Hi, Some of the jobs you submitted lately have failed -- please make sure that the sequence files you submit have an extension -- '.fasta' will do. For example, 'metagenome_sequence.fasta' and resubmit them to the MG-RAST server. Please do inform us if you continue to have problems with the upload. -- Regards, Mark D'Souza -- for the MG-RAST team [email protected] http://metagenomics.nmpdr.org/
