Dear @LISA_mri_challenge, I hope you are doing well. I previously submitted my hippocampus segmentation model during the validation phase and it worked as expected. Recently, I made some updates and adjusted the output files accordingly. Although the naming and file formats match your requirements, I encountered an error when trying to submit the updated version. As a result, I had to submit the earlier working version. **Your workflow job, (submission ID 9758197), has failed to complete. The message is: ore.cwl/instance-a_vlpv7_ with ID kind-file_var_lib_docker_volumes_workflow_orchestrator_shared__data_b1ee55d5-30af-4854-9d40-ed9eee7b9419_LISA_infra-main_wf-Task2a_steps_score.cwl/instance-a_vlpv7_ to 0 STDERR: 2025-08-31T20:38:20.656808268Z** Now, as I move on to the test phase, I would like to use the updated version, but I want to ensure it will not cause any submission issues. My question is, is there any way I can share or test this updated version in a similar validation environment before the final test submission? I just want to confirm that the updated results will work correctly and meet your requirements so that I don't run into any unexpected errors. I appreciate your guidance and any suggestions on how I can verify the updated version before proceeding. Thank you very much!
