Dear AFNI experts
I have t-maps resulting from 1st-level analysis (GLM) in the SPM package. I mapped the data on a surface, smoothed the t-maps using SufSmooth in AFNI. However, I am not sure whether it is correct to smooth t-maps (I did not smooth data during preprocessing) as it is common practice to smooth data during preprocessing. Do you think it is ok to smooth t-maps? Do you know any study that has smoothed t-maps?
I smooth the t-maps with the t-maps with the following command:
SurfSmooth - spec surf.spec
I did not use -blurmaster because I did not process the data in AFNI, and I did not have residual time-series (errts) from 3dDeconvolve. Also, I don’t know what blurmaster is doing. Is it correct to smooth the surface without blurmaster and with the above script?
