- For ungated list mode files, each challenge will include 2-3 "virtual tubes" performed by a 6-color method. The participant will download the files from a CAP website and analyze the data on a MAC or PC using standard software, including FlowJo, FACSDiva, Kaluza, Woodlist, etc. The files will be large as each tube will have collected hundreds of thousands of events. Boolean gating will be necessary to see if there is an atypical population.
- Demo list mode files are available for download to determine software compatibility prior to enrollment. Go to fileshare.cap.org (username: demo-b-all-mrd; password: ProductTest1).
