What is a .FQ file?
FQ is a FASTQ file of sequencing reads with quality scores.
- Did you know
- FASTQ pairs each read with quality scores showing how confident the sequencer was.
- Each FASTQ entry uses four lines: an identifier, the sequence, a separator and a line of per-base quality characters.
- The format originated at the Wellcome Trust Sanger Institute to keep reads and their quality scores together.
- What Analyser reads
- Open scientific, medical and engineering files: DICOM scans, NIfTI brain volumes, Garmin FIT/TCX activities, FITS astronomy frames, FASTA/FASTQ sequences, chemistry structures (MOL/SDF/MOL2/CIF/XYZ), Gerber/Excellon PCB data, SPICE netlists, EDF/BDF biosignals, JCAMP-DX spectra, SPSS/Stata/SAS datasets and VTK/ParaView meshes - metadata extracted entirely in-browser.
- Depth of analysis
- .FQ is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .FQ file
- Drag a .FQ file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
