Summary: Get a genome sequence report by genome assembly accession
Operation ID: genome_sequence_report
Auth: unknown
Description

Get a genome sequence report by genome assembly accession. By default, in paged JSON format, but also available in tabular (accept: text/tab-separated-values) or JSON Lines (accept: application/x-ndjson) formats.

Parameters (8)

accession (string, path, required)

One or more genome assembly accessions, limited to 100

chromosomes (array, query, optional)

Limit to sequences with the specified chromosome names

count_assembly_unplaced (boolean, query, optional, default: False)

Include the count of unplaced scaffold sequences

include_tabular_header (?, query, optional)
page_size (integer, query, optional)

The maximum number of genome assemblies to return. Maximum is 1000. If the number of results exceeds the page size, `page_token` can be used to retrieve the remaining results.

page_token (string, query, optional)

A page token is returned when the results count exceeds `page size`. Use this token along with previous request parameters to retrieve the next page of results. When `page_token` is empty, all results have been retrieved.

role_filters (array, query, optional)

Limit to sequences with the specified "role", where possible roles are `assembled-molecule`, `unlocalized-scaffold`, or `unplaced-scaffold`

table_fields (array, query, optional)
