Output Files

These links permit you to directly download the data and report files.Some files are compressed, using the .zip format, to provide data integrity and to reduce download time.

Click on a file type button to save the file to your local computer.Most outputfiles can be loaded into third-party viewers (such as IGV) for visualization. The barcode row only appears for runs on barcoded data.

Files in the barcode row are zips of one file per active barcode. To download only BAM and BAI files for a single barcode, go to the barcode section at the top of the run report (see Barcode Reports ).

Column Description
Reads Files with unaligned reads (before alignment)
Aligned Reads Files with aligned reads
File type Reads Aligned reads
BAM

Unaligned reads in BAM format.

In this release, the BAM file contains some flow space information.

Aligned reads sorted by reference location.

See Run Metrics Overview for a description of the alignment data included in this BAM file.

BAI BAM index file

The BAM format

Binary Sequence Alignment/Map (BAM), is a compressed, binary form of the SAM format. BAM files can be indexed, using the BAM Index file, for quick access to sequence alignment data. See http://samtools.sourceforge.net for more a more detailed description of the SAM/BAM file format. Many tools are available for working with SAM files.

Deprecated file formats

The following file formats are deprecated and not produced by the default analysis pipeline. The FileExporter Plugin optionally generates these files.

The SFF and FASTQ files created by the FileExporter Plugin are generated in the plugin directory , not in the main analysis directory

File type Description
SFF

Compressed (.zip) Standard Flowgram Format (SFF) -formatted file that contains "flow space" data.

The bases called in a run are stored in two formats: SFF and FASTQ. Both files contain the nucleotide calls and associated quality values, the SFF files, additionally, contain signal values in flow space and a mapping between sequence and flow spaces.

The data are organized on a per flow basis, and contain information about nucleotide flows that both did and did not result in base incorporation. (See Technical Note - Filtering and Trimming .)

Note: The SFF file format is deprecated and not produced by the default pipeline.
FASTQ

Compressed (.zip)FASTQ-formatted file containing data organized in a per-base basis, including quality scores. The reads contained in the file are unaligned reads. (See Technical Note - Filtering and Trimming .)

Note: The FASTQ file format is deprecated and not produced by the default pipeline.

Rename your output files

See the FileExporter Plugin supports renaming your putput files. (This plugin also optionally creates SFF or FASTQ formats, or zips your output.)
