> Is there any method to plot coefficient, SD/SE of this effect '-gltCode ... 'CiJi : 1*anode QainHou : 1*after Contrast3 : 1*now'?
Each post hoc inference through -gltCode gives you two values per voxel: effect estimate and t-statistic. You can directly obtain the standard error (dividing effect estimate by t-statistic). Once you have the standard error, I think there is a way to plot the result at the voxel level although I don't know the detail on the AFNI GUI. For ROI-level plotting, do it with a graphical tool after extracting the resutls.
