RE: Metaregression images interpretation for single study - and categorical variables
Thank you Lyda!
That is really helpful; I had been trying to perform the differences analysis with two separate meta-analysis results (i.e. not combining them into one).
I have now combined them as you say, but the resulting '*_1m0_z_p.nii' has no activations. What's strange is that one a threshold it, the resulting '*_1m0_z_p_0.00500_1.000_10' map shows multiple widespread activations - many of which ook almost identical to the conjunction analysis (so that the differences map looks almost the same as the convergence map...). Are you not supposed to threshold this map? Perhaps it is already thresholded if it draws from a thresholded main analysis map?
Thanks for your help
All the best,
Molly
