Hi everyone! Please make sure you are submitting your actual submission file and not the Synapse folder or Synapse project it is in. Using the challenge template as an example: [This](https://www.synapse.org/#!Synapse:syn16809532) is the folder the file is in (incorrect). [This](https://www.synapse.org/#!Synapse:syn16809883) is the actual file (correct). When making a submission using the button [here](https://www.synapse.org/#!Synapse:syn15667962/wiki/588191), you'll want to select the file, not the project or folder your file is in. The selection page will look something like this: - Project - Folder - **Prediction_file** Make sure the actual file is selected(in bold).
