Services: IntervalFrequencies

This service provides access to binned CNV frequency information of data “collations” in the Progenetix project databases. A typical use would be the retrieval of data for a single collation, e.g. by its identifier (e.g. NCIT:C7376, PMID:22824167, pgxcohort-TCGAcancers).

NCIT:C4893	Benign Urinary System Neoplasm	93	0

Response Types

Download .pgxseg files

.pgxseg files are tab-delimited, columnar text files where each line provides information about features or measurements associated with a genomic region. More information can be found on the file formats page.

Stream JSON data

JSON formatting is provided in a Beacon v2 response, inside the results array. Each frequency set is provided as object, with the single bin frequencies in interval_frequencies. For more information see the beaconresponse json documentation.

For the usual “single frequency set” use case this would result in a possible direct access to the frequecy list at results[0].interval_frequencies.
