Hi, I'm following instructions at https://github.com/apetkau/galaxy-hackathon-2014. When I try to run the concatenate-datasets on two input files, two odd things happen. First, TWO nearly identical commands are generated in the History panel, only differing in their output filename. In paster.log, only the second one shows up. Second, the program fails, with this info in the History: An error occurred with this dataset: Galaxy slots passed through contain as 1 /inside/home/jeltje/exp/varscan2/programs/galaxy-dist/database/job_working_directory/000/10/container.sh: line 2: can't create /inside/home/jeltje/exp/varscan2/programs/galaxy-dist/database/files/000/dataset_14.dat This happens for both commands in the History panel, only the output filename in the other error is dataset_15.dat Oddly, the dataset_14.dat and dataset_15.dat are both created during this command, they just end up empty.
