INTRODUCTION INTO TAVERNA
2What is TAVERNA ?
3Motivation
Web Services to performe Such analysis exist
keyword
get sequences
They are highly distributed And required
programming knowledge to link them To a workflow
Multiple seq Alignment
output
4Motivation
What if a lab scientist without/with little
programming knowledge also wish to run such
experiments ?!!!!!!
The Taverna project has developed an open source
tool, which enable scientist to orchestrate
bioinformatic Web services in workflow without
been confronting to technical details and
complexity of web service programming!!!

Default initial services to be loaded at start
can be configured in the mygrid.properties file
