Hi, Is there more documentation on the topic of "custom display applications"? I only found http://wiki.g2.bx.psu.edu/Admin/Tools/External%20Display%20Applications%20Tu... which has a few examples, but these are incomplete. For example, they use some variables like ${BASE_URL} and ${DATASET_HASH} but I cannot find extra information on these and if there are more variables which I could use. Basically I want to build a tool which also its own display application next to the normal textual output file. Thanks and regards, Pieter Lukasse Wageningen UR, Plant Research International Departments of Bioscience and Bioinformatics Wageningen Campus, Building 107, Droevendaalsesteeg 1, 6708 PB, Wageningen, the Netherlands +31-317480891; skype: pieter.lukasse.wur http://www.pri.wur.nl<http://www.pri.wur.nl/>
