BedGraph format. BedGraph is a suitable format for moderate amounts of scored data. It is based on the BED format (see above) with the following differences: The score is placed in column 4, not column 5; Track lines are compulsory, and must include type=bedGraph. Currently the only optional parameters supported by Ensembl are: name - see above

bedtools genomecov computes histograms (default), per-base reports (-d) and BEDGRAPH (-bg) summaries of feature coverage (e.g., aligned sequences) for a given genome.

Producing BEDGRAPH output; Sophistication through chaining multiple bedtools; Principal component analysis. A Jaccard statistic for all 400 pairwise comparisons. Puzzles to help teach you more bedtools.

Step 1 for generating bigWig files is to convert the BAM alignment results to a bedGraph (with extension bg) file that contains coverage along genomic regions. Enhancing your vocabulary: Example BED file below -- https://bedtools.readthedocs.io/en/latest/content/tools/genomecov.html.

BED (Browser Extensible Data) format provides a flexible way to define the data lines that are displayed in an annotation track. BED lines have three required fields and nine additional optional fields. The number of fields per line must be consistent throughout any single set of data in an annotation track.

BedGraph format. In addition to accomodating peak calls (discrete data), the BedGraph format also allows display of continuous data as a track on a genome browser. This display type is useful for including and plotting some quantitative information, e.g. intensity.

A BEDGRAPH file is a text file used to display quantitative data across genomic intervals. It's structured with four tab-separated columns: chromosome, start position, end position, and signal value.

If your data is sparse or contains elements of varying size, use the bedGraph format instead of the wiggle format. If you have a very large bedGraph data set, you can convert it to the bigWig format using the bedGraphToBigWig program. For details, see Example Three below.
