Thank you both for your suggestions. I finally managed to read everything. I first removed the underscore from the data directory, as suggested by Mark, but this did not change anything. I previously tried to place the sampleSheet file both in the data folder and one level up, with no result. The clue was apparently to move the txt data files one level up and avoid a separate file for the data. Do you think that it did not like to have a folder starting with the same number as the data files? I love that the problem is fixed, but i hate not knowing why? best, Christine 14. aug. 2014 kl. 17:16 skrev Mark Dunning <mark.dunning at="" gmail.com="">: > You should probably try renaming the directory 9031292034_data to 9031292034.
