- +===== How to test stripping lines on the GRID ===== 
 +First you have to make sure, the SDSTs as well as the RAW files are accessible and are staged in (as in the test-samples). 
 +In ganga then you can do the following (in addition to the usual things): 
 +<code python> 
 +j.inputdata = DaVinci().readInputData('/someDirectory/something_SDST.py') 
 +j.inputdata.depth = 2 
 +</code> 
 +where it is crucial that you set ''j.inputdata.depth = 2'' to make sure the RAW files can be accessed.
