FASTQ File Upload Requirements

The FASTQ file is a text format file used to represent sequences. Each record has four lines of data: an identifier (read descriptor), the sequence, +, and the quality scores. For a detailed description of the FASTQ format, see FASTQ Files.

Make sure the FASTQ file adheres to the following upload requirements:

FASTQ files are generated on Illumina instruments and saved in gzip format
The name of the FASTQ files conforms to the following convention:


The read descriptor in the FASTQ files conforms to the following convention:

@Instrument:RunID:FlowCellID:Lane:Tile:X:Y ReadNum:FilterFlag:0:SampleNumber:

Quality considerations:

The number of base calls for each read equals the number of quality scores.
The number of entries for Read 1 equals the number of entries for Read 2.
The uploader determines whether files are paired-end based on matching file names in which the only difference is the ReadNum.
For paired-end reads, read 1 and read 2 files need to be uploaded together or can be combined later.
Each read has passed filter.
