20
Biologist’s Outlook Results available for subsequent analysis Data and results are of great interest
21
eScientist’s Outlook Microbase simplified data analysis But … Autonomy - most services provided originally by external parties Licensing – limits exposure of services Distribution - difficulty came from the relatively large datasets
22
Future Enhancements Use notification to automatically analyse recently annotated genomes Migrate workflows to a remote enclosed environment?
23
