Although the XML format for pipeline configurations is straightforward, it is easiest to start with a pre-existing XML file. From the "Configure Pipelines" page it is easy to browse and download XML configuration files for all of GLAST's pipelines. Click "View" next to the pipeline to view the XML configuration file in your browser. Click "Download" to download the XML configuration file in text format for easy editing in your favorite editor.
You must be logged in to upload an XML configuration file. If you are not logged in, you will see "Login" in the left hand navbar. If you are already logged in, you will see "Logout" followed by your user name. You will only see the "Click here to upload a new configuration file" link on the "Configure a Pipeline" page if you are logged in. Click the link (indicated in the screenshot below), to be taken to the page that allows you to browse your local hard drive for a pipeline XML configuration file to upload.
How to Define a Pipeline
A GINO Pipeline is defined in an XML file whose format is described by a W3C XML Schema available at http://glast-ground.slac.stanford.edu/pipeline/pipeline.xsd. This schema will mainly be useful if you use an XML editor that supports W3C XML Schema, which these days includes nearly all modern XML editors. XML Spy is a good choice that we have experience with. However, most pipelines will be easy to configure with a simple text editor (emacs for example).
