Hello! Here are some general tips for submission:

  1. Take the following steps to reduce file size: 1) cast all values within the deformation field to 32-bit floats, 2) round the resulting values to two decimal places, and 3) create the .h5 file with gzip compression. For an example on how to do this please look at our script that generates an example submission.
  2. Make sure you are a verified user of Grand Challenge. Unverified users have an upload limit of 2GB per upload, while verified users have an upload limit of 10GB per upload.
  3. Make sure that you are not going over the maximum number of allowed submissions per leaderboard per day (4).

We have also extended the submission deadline! **The three leaderboards will now close on March 15th. **
