outputbedGraph
outputbedGraph refers to bedGraph-formatted data produced as output by a genomic data analysis workflow. bedGraph is a simple, plain-text format used to display a continuous-valued signal across genomes, such as read coverage, expression estimates, or ChIP-seq intensity. An outputbedGraph file typically contains four tab-delimited columns: chromosome, start, end, and the numeric value for that interval. Start positions are 0-based and inclusive, end positions are exclusive, following the BED coordinate convention. Values may be integer or floating-point, depending on the source data. Data are often sorted by chromosome and start position to enable correct visualization in genome browsers such as UCSC Genome Browser or IGV. A track line with browser directives may precede the data, but it is optional.
In practice, outputbedGraph is generated by pipelines that compute a signal along the genome and emit one
Key considerations for outputbedGraph datasets include ensuring proper sorting, matching chromosome naming conventions, and validating that
