Help: You can use the following existing task, 150626_112217:atanasi_crab_CRAB3_Advanced_Tutorial_June2015_Exercise3C, which represents the exact situation described in 3.C. Doing crab remake --task 150626_112217:atanasi_crab_CRAB3_Advanced_Tutorial_June2015_Exercise3C you will create a CRAB project directory for this task, at which point you will be able to execute crab commands referring to this task. You can then submit your proposed recovery task. Will it publish in the same output dataset?
