Query-based histograms

Direct generation of histogram plots from Beacon queries

So far, the plot API only provided (documented) access to generate CNV histogram plots from "collations" with pre-computed frequencies. The bycon API now offers a direct access to the histograms, by adding &output=histoplot to a Beacon (biosamples) query URL. The server will first query the samples and then perform a handover to the plotting API. Please be aware that this procedure is best suited for limited queries and may lead to a time-out.

Example (some loading time)

• progenetix.org/beacon/biosamples/?referenceName=9&variantType=EFO:0030067&start=21500000&start=21975098&end=21967753&end=22500000&filters=NCIT:C3058&filters=pgx:cohort-celllines&output=histoplot
  • a search for samples with focal deletion in the CDKN2A locus, limited to glioblastoma cell lines
