To add services:
- In Taverna 2.x, click on the Import new services button above the Available Services tree in Service Panel and select the appropriate service type. In Taverna 1.7.x, right click on Available Processors and add a new service by selecting the particular type and supplying the address, or you can scavenge for new services at a specified Web address.
To remove services:
- Right click on the service node and select the service you want to remove from under Remove individual service provider (Taverna 2.x) or Remove from tree (Taverna 1.7.x).
In Taverna 2.x, any service you add (through a service provider) to the Service Panel will be remembered next time you start Taverna. If you want to remove such a service, simply right click on it in the Service Panel and remove the corresponding service provider. Note that removing a service provider will remove all services added though it (if there were several), and not just that one service. You can also remove all services you added at once, so only the default ones will remain.
In Taverna 2.x, you can also remove the default set of service providers and restore them later on. This is done in a similar fashion by right-clicking and selecting an appropriate option from the pop-up menu. You can further configure the behaviour of default service providers through Preferences (File > Preferences > Service Providers).
In Taverna 1.7.x, even if you remove default services, they will be reloaded next time you start Taverna. To prevent services from being loaded at startup, you can alter the configuration in the mygrid.properties file. This file is found in the conf/ directory within the Taverna startup directory or within your Taverna home directory if you wish to specify specific user settings within a multi-user environment.
