Genomic intervals & annotation / BED merge
Your data stays in your browser: files are read and processed on your device, never uploaded to any server, and cleared when you close the page. Free, no sign-in.
Intervals are sorted by chromosome and start first; overlapping or book-ended intervals (one ends where the next starts) become one region, and a merge distance also joins nearby intervals.
With strand-specific merging, + and − strands are merged separately and intervals without a strand are left out; the table gains a strand column while the BED text keeps three columns plus summaries.
Summary columns are computed over the original records in each region: “collapse” on the name column lists the merged genes; “mean” or “maximum” summarise a score. Numeric summaries ignore non-numeric values.
The bar chart shows how many original intervals each merged region holds: mostly 1 means scattered intervals; many ≥2 means clustering.
A single sweep after sorting; summary operations and number format (10 significant digits) match BEDTools merge (Quinlan & Hall 2010, Bioinformatics 26:841), checked line by line on the same inputs.
Runs in your browser; up to roughly 50 MB (a few hundred thousand intervals) is recommended.
