Systems Biology Validation Service (SyBValS) is a web service to validate the maps in SBGNML format and to produce graphical images of the map with an option to highlight errors. After validating maps, if desired, SyBValS will resolved these errors when possible, again producing an image of the map after any fixes. This page presents a sample client-side demo for SyBValS.

To use the demo, please follow these steps:

• Open a file in SBGNML format (or open one of the sample files provided).
• Select an image format and change any image options as desired.
• Click on "Validate Map" button to validate the map.
• Now you can view/download error information under the "Errors" tab and the corresponding image in the "Image" tab for the validated map.
• If desired, click on "Resolve Errors" button to resolve errors when possible. When multiple fixes are possible choose the desired one from the error list.
• Now you can view/download the updated error info in "Errors" field and corresponding image under the "Image" tab for the map after resolving errors. You can also download the SBGNML file after errors are resolved.

A video illustrating how to use this demo can be found on YouTube.
