Decoder "internal server error"

[Amber Gonzalez]

Hello, 

I am trying to use the decoder feature on neurosynth, but no matter what I try, the page returns to "Internal server error." I believe I am filling everything out correctly. I am using a Z map image, fMRI BOLD, and I am uploading the unthresholded .nii.gz format of my image.

Any help what might be wrong here???
