Hello, I used the following command to create my tarball file as instructed in [this](https://docs.medperf.org/concepts/mlcube_files/) link: ```tar -czf additional_files.tar.gz -C /workspace/additional_files .``` However, I am getting that the tarball submission is invalid when i submit to the challenge. I was wondering what files if any I should include other than the mlcube.yaml file in the tarball. Thanks, Anita

@i_sahajmistry , Apologies for the troubles. You must submit your Docker image to the queue name: "BraTS 2023: Docker Images" Otherwise, if you submit it to the MLCube queues, the submission system will trigger the workflow and invalidate your Docker submission.
@hasank I have create a tarball using the instructions mentioned on the page. The tarball contains all the required files namely ```mlcube.yaml``` and ```additional_files.tar.gz``` where ```additional_files.tar.gz``` contains the checkpoint the only additional requirement for the model to run. I have uploaded both ```nnunet_gli.tar.gz``` and simultaneously pushed the docker image to synapse. I submitted the both docker image and ```nnunet_gli.tar.gz``` in same order with same name i.e ```nnunet_gli```. I am still getting the submission invalid. @vchung @ujjwalbaid
Hello @anitakriz, The tarball submission should not be `additional_files.tar.gz`. Please read again the instructions carefully. What you are required to submit is the tarball mentioned [here](https://docs.medperf.org/concepts/mlcube_files/#preparing-an-mlcube-for-hosting). The final tarball to be submitted should include `mlcube.yaml`, and if needed, `parameters.yaml` and `additional_files.tar.gz`.
Hi @anitakriz, If you have Python available on your machine, I recommend following [these instructions ("Preparing an MLCube for hosting")](https://docs.medperf.org/concepts/mlcube_files/#preparing-an-mlcube-for-hosting) instead to prepare your MLCube. This tool will find all of the required assets and will compress them into a single tarball that you can then upload and submit on Synapse. Let us know if you are still experiencing issues!
