I am trying to submit my first docker image to the express lane. I have pushed the image to my synapse repository. However when I submit a text file containing the following line: preprocessing=docker pull docker.synapse.org/syn8096691/docker_preprocess_png@sha256:6a293a23222b8ebff26f5110bc2515e7f2a5a4f86c24ffbce0f6280b76064de2 I get the following error: Dear SciLifeLab: Your Submission to the Digital Mammography challenge, syn8096992 (ID 8096993), was invalid. The message is: docker pull docker.synapse.org/syn8096691/docker_preprocess_png@sha256:6a293a23222b8ebff26f5110bc2515e7f2a5a4f86c24ffbce0f6280b76064de2 is not a valid Docker commit. Must be [host/]path@sha256:digest Please direct any questions to the challenge forum, https://www.synapse.org/#!Synapse:syn4224222/discussion. Sincerely, Challenge Administration The address looks according to the template to me and I have pulled the same address (with the digest) successfully on my local machine. Also, I have shared the project with dmchallengeit. What am I doing wrong here? Thanks for any help!

Oh, wow, such an obvious mistake! Thanks!
Hello, try preprocessing=docker.synapse.org/syn8096691/docker_preprocess_png@sha256:6a293a23222b8ebff26f5110bc2515e7f2a5a4f86c24ffbce0f6280b76064de2 instead. The command "docker pull" should not be in the submit file.
