Training delivery
• TWB uses a lot of software, can be time-consuming to install, so we put it into a Virtual Machine (VM).
A VM is a copy of Windows running inside Windows. (or Windows inside MacOS, or Linux)
• Saves a lot of time & makes it easy to experiment with workflows• Don’t use for production modelling.• We can give VMs to CSIRO staff, not others.• ArcGIS licence times out on Friday!

Module 3: The TWB software toolshttps://wiki.csiro.au/display/HWB/The+TWB+software+tools
• This will be a quick run-through. See module 3 for more details.• Import package loads a collection of predefined activities • Backup registry saves the current state of the Trident registry.• Restore registry loads a previously-saved registry. • Find lets you search for activities & workflows• Generate activity “wraps” external things (R/Python scrips, Source
projects etc) and imports them into Trident.• Logs opens Windows Explorer at the logs folder (Source/Trident)• Workflow composer opens Workflow composer (creates
workflows)• Management studio adds/removes categories, individual activities
