Submission Q & A

Q: I'm getting the error "upload limit reached" when I try to upload my zipped submission file. 

A: 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. Also make sure that you are not going over the maximum number of allowed submissions per leaderboard per day (4). 

Q: How do I reduce my submission file size?

A: Make sure you're taking 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.
