I was wondering, if anyone could point me to any resources and that allow the user to interact with the view of the output of a tool in Galaxy. So for example, I would like to load an image, draw a region of interest (ROI) (probably via some js routine) and then store that information in a file, generating an input in the History view. This input could then be used for further analysis.
I guess Trackster does something like this, but I don't know if its routines are generic enough to handle this type of interaction.
Thanks for any info!
