**Question:** Can the content of /preprocessedData be updated, meaning adding new data and not deleting the old one? **Answer**: Not in the current implementation of the system. Note that the pre-processing step must always be uniquely defined in your training submission file because the persistent storage of the pre-preprocessed data is not guaranteed as there are less 10 TB partitions available than the number of participants registered. If you only need to slightly update the pre-processed data, you may do it in the training container and save the result to the scratch space `/scratch` (see documentation).
