Dear List,

I'm trying to conduct meta-analytical decoding on my own data using Neurosynth's decoder. I have uploaded my Tmap images in neurovault (.nii.gz format, MNI template; tried both as private and public collection), but whenever I paste the full link from neurovault into the neurosynth decoder, or use the option 'Analysis - Cognitive decoding (neursoynth) within neurovault, I get the error: 502 Bad Gateway (nginx/1.21.6). 

Does anyone know what causes this error and how to fix it? Thanks a lot in advance!

best,
Iris

There was a file space issue, it should be resolved now if you could try again, sorry for the long delay.

Dear developers:

I tried to use the decoder part in Neurosynth, but it seems can't be used after filling in the information. I saw this queation in Git-Hub last month, too. And it still showed "Server Error (500)".  How can I solve the problem? If you have better solutions please tell me. I am stuck for a couple of days and I am eager to test a result of mine. Thank you!

Best,
Yanmiao Yang

Hi Yanmiao Yang,
Thanks for reaching out!

What is the file that neurosynth is unsuccessfully decoding? Is it a 3D nifti file? Here is a currently working example: https://neurosynth.org/decode/?url=http%3A%2F%2Fneurovault.org%2Fmedia%2Fimages%2F17216%2FspmT_0006.nii.gz

Thanks!
James
