I have no idea about that 3 of 4 submission files failed to get cmap or rmap score even they are in right format.
I will leave to organisers of the challenge to confirm.
But as far as I see, you have predicted
whcsp in some cases which is not a valid code. The valid name are
whcspa1. Due to which submission has failed.
I will check the ebird codes in submission files.
I have successfully submitted several submission files, but got 0 cmap scores of all. Is there some thing wrong with my submission files or they were just calculated to be 0?
