This loads all **32 TCGA PanCancer Atlas** cohorts (~10,950 samples total, note overlapping cohorts aren't an issue here since these are 32 distinct tumor types) with **EGFR, ERBB2, ERBB3, ERBB4** queried together. **To merge the four gene tracks into one row:** in the OncoPrint, click the small gear/menu icon on the left edge of the gene tracks panel and select the tracks (or use the "..." menu on any one track) → **"Merge tracks"** (sometimes labeled "Group"). This combines EGFR/ERBB2/ERBB3/ERBB4 into a single collapsed row showing "at least one altered" per sample — this is a client-side toggle in the oncoprint UI and isn't something a URL parameter can set directly, so this one click is needed after the page loads.
