How can I get the P value for cognitive decoding function in Neurovault?

Dear experts:
How can I get the P value for cognitive decoding function in Neurovault? You only povide the r value,but no P value.

Just to clarify - cognitive decoding is currently provided by Neurosynth not NeuroVault. As far as I know they do not provide p-values right now.

We don’t provide p-values, as there’s no obvious way to efficiently compute a meaningful p-value for this particular statistic.
