Hi organizers, I have a couple of clarifying questions about the Task 1 submission process: 1. For the Docker evaluation queue: can a team submit more than one Docker image over time, or is only a single final submission evaluated? If I submit a container now and later submit an improved version before the deadline, does the newer submission replace the earlier one, or would both be evaluated? 2. Could you clarify the relationship between the two queues on the Task 1 submission page (the "predictions" queue and the "Docker" queue)? My understanding is that the predictions queue corresponds to the validation leaderboard (for development feedback), while the Docker queue is the one used for the final ranking on the hidden test set, is that correct? 3. Just to confirm: is there any limit on how many Docker images we can push to our own Synapse project registry (as opposed to how many we submit to the evaluation queue)? Thank you for your help. I want to make sure I follow the correct process before the deadline. Best regards, Andres

Hi @afromerogr , > The submission with the UI there is the final one, and the one we only have one shot for correct? Also do we get a confirmation that you have received said Docker upload from the UI the way we do with validation uploads? Yes, the Docker queue has a submission quota of 1 submission total. Just like with the validation leaderboard, you will get an email notification when your Docker model is received. Please keep in mind that this email only confirms receipt, not execution. So before submitting, we highly recommend testing your container locally on the track’s validation dataset to verify that it executes properly and outputs predictions in a flat structure. Hope this helps! EDIT: markdown formatting
Hi @astaraki, https://github.com/IUCompPath/BraTS-Path-2026-Docker-Submission-Kit Regarding the docker submission toolkit for Path track, whether should I push the docker image to the synapse project repository or upload a tar file? If upload a tar file, where should I upload it? If push a docker file, what I should guarantee is the docker image can produce prediction files in the mounted output directory, is that right? Regards, Ke CHEN
Thanks for the reply Mehdi! @astaraki Quick follow-up out of curiosity, my Docker has been pushed by the command_line and sits in the Docker Repository. The submission with the UI there is the final one, and the one we only have one shot for correct? Also do we get a confirmation that you have received said Docker upload from the UI the way we do with validation uploads? Regarding the OpenReview Paper in order to link it is with the Team Name that is displayed in the validation leaderboard? 'BraTS Uniandes' in my case. Best regards, Andres
Hi @afromerogr Thanks for reaching out. 1- Please note that each team is allowed to submit one single Docker image per task. Your Docker image will be executed only after the submission deadline; therefore, we will not be able to provide you with feedback about the status of your Docker image. As announced [here](https://challenges.synapse.org/Challenges/DetailsPage/News?id=syn74274097) we highly recommend testing your solution locally and then pushing your Docker images. 2- You are right. You should follow the Docker queue for the testing phase submission. "Uploading a Docker image requires using the terminal rather than clicking an upload button. To push your image to your Synapse project, the name must be prefixed with: ``` docker.synapse.org/YOUR_PROJECT_SYNID/. ``` " 3- You may be able to use TAG to update your Docker image, but note that only the latest version will be executed. Best regards, /Mehdi
