+ "Archive generated fastq file format\n"
+ "Data format\n"
+ "Read data including bases, base qualities and alignments can be submitted in several different formats ... more information.\n\n"
+ "Metadata format\n"
+ "The metadata model consists of several objects each represented using XML ... more information.\n\n"
+ "Accession number format\n"
+ "Each metadata object is assigned a unique accession number by the archive. The accession numbers can be used to retrieve data and metadata using the EB-Eye search available at the top of all EBI web pages or using the free text search available on the ENA home page. The metadata is then retrieved and displayed through the ENA Browser as in the examples in the above table.\n\n"
+ "Accession numbers assocaited with read data assigned by EBI start with 'ER' and accession numbers assigned by NCBI and DDBJ start with 'SR' and 'DR', respectively. The third letter of the accession number indicates the type of the metadata object. EGA accession numbers start with 'EGA' with the fourth letter indicating the type of the metadata object.\n\n"
+ "The accession numbers have a fixed number of digits after the letters: six for ENA and eleven for EGA.\n\n"

+ "Once made public, data submitted to ENA are available for download using ftp and Aspara. Detailed data download instructions are available here. Currently, both submitted data files and archive generated fastq files are made available for download. The naming and format of the generated fastq files are described below.\n\n"
+ "In general, one fastq file is created for each application read in a run. Please refer to the table below for full details:\n\n"
+ "Number of application reads Fastq Files Description\n"
+ "1 \n"
+ "<run_accession>.fastq.gz\n"
+ "or\n"
+ "<run_accession>_1.fastq.gz\n\n"
+ "For experiments with single application reads only all reads will be made available in one fastq file.\n"
+ "2 <run_accession>_1.fastq.gz\n"
+ "<run_accession>_2.fastq.gz\n"
+ "<run_accession>.fastq.gz For paired experiments with two application reads reads will be made available in 1-3 fastq files. If a paired experiment is submitted with both application reads then the first reads will be in <run accession>_1.fastq.gz file, the second reads will be in <run accession>_2.fastq.gz, and any unpaired reads will be in <run accession>.fastq.gz file. In case a paired experiment is submitted containing only unpaired reads then only a single file will be created: <run accession>.fastq.gz.\n"
+ "> 2 <run_accession>_N.fastq.gz For experiments with more than two application reads (e.g. Complete Genomics or strobed PacBio) one fastq file is created for each application read, however, no empty fastq files are created.\n"
+ "The fastq file format is:\n\n"
+ "@<run accession>.<spot index>[ <spot name>\\[/<read index>\\]]\n"
+ "<bases>\n"
+ "+\n"
+ "<phred qualities, ASCII encoded starting with '!' (33)>\n"
+ "Field Description\n"
+ "<run accession> The Run accession. A spot is identified uniquely by the combination of the Run accession and the spot index.\n"
+ "<spot index> A positive integer assigned to the spots in the order in which they appear in the run. A spot is identified uniquely by the combination of the Run accession and the spot index.\n"
+ "<spot name> The spot name as it was provided by the submitter. In cases where the read name is missing or was removed by the archive this field is not present.\n"
+ "<read index> A positive integer assigned to the application reads in the order in which they appear in the spot: /1 for first application read and /2 for the second application read. In cases where the read name is missing or was removed by the archive this field is not present.\n"
