While studying file-access graphs in O2DPG MC, I noticed that trdtracklets.root get written twice: One from the digitizer workflow and once from the TRD-DIGI-QC task. This can corrupt the processing and is probably a bug. QC should only read digits/trdtracklets. The reason appears to be the use of `o2-trd-trap-sim` as the reader command for digits and tracklets. For now, the problem can probably be avoided by using `o2-trd-trap-sim --disable-root-output true`. However, this might still create new trdtracklets in memory which should not be needed as they have been previously created during digitization. So it would be good to just use a true `o2-trd-sim-artefacts-reader` workflow or similar in the future.
