about how to report results after 3dMVM

hello AFNI experts:
sorry for bothering again and thank you all for all the help!
i’ve known that after the analysis, i’d better use the ‘coef’ brick as the olay and ‘stat’ brick as the THr. but after MVM, there is no more ‘coef’ or ‘stat’. i just have the name of my gltlabel and the label with a ‘t’, like ‘XXX’ brick and ‘XXX t’ brick. what should i set as Olay and THr?
and i’m not very sure about how i should set the p value to see the activations. have the the results of 3dMVM already pasted the fdr correction or not? or should i run the 3dclustsim after 3dMVM? thank you so much!

Use the ‘XXX’ sub-brick as overlay and the ‘XXX t’ sub-brick for thresholding.

You can report the result with the correction based on FDR if you’re happy with it. Or you can adopt cluster-based correction through 3dClustSim. Either way is acceptable in the field.
