• As of release 17.09, fastq data will have the datatype fastqsanger auto-detected when that quality score scaling is detected and “autodetect” is used within the Upload tool. Compressed fastq data will be converted to uncompressed in the history.
• To preserve fastq compression, directly assign the appropriate datatype (eg: fastqsanger.gz).
• If the data was already loaded as fastq.gz, don’t worry! Just test the data for correct format (as needed) and assign the metadata type.
