Python (gwplot)

The gwplot package is a Python interface to GW’s renderer. The gwplot API is unchanged in v2 — existing scripts keep working.

pip install gwplot

from gwplot import Gw

gw = Gw("hg38")                    # reference genome tag or fasta path
gw.add_bam("sample.bam")
gw.add_track("variants.vcf")
gw.add_region("chr1", 1000000, 1100000)
gw.save_png("output.png")

Themes save/load with save_theme_to_json / load_theme_from_json — the same .gw.theme.json format as the desktop app (see Settings).

To serve GW views to many clients, gwplot sessions can back the remote viewer protocol by implementing the Backend interface in deps/protocol/viewer/v1 (importable as protocol.viewer.v1 with deps/ on sys.path).
