Hi AFNI Guru,
I used a fast event related experiment design and showed 64 images in each run, and in total there were 6 runs. I have come across the paper by Mumford (2012) when I searching the best way to evaluate beta values for each of my 64 images. In the paper, they suggested using a LSS, which could be handled by 3dDeconvolve + 3dLSS. I have read the help for 3dLSS and searched in the forum for a example how to use this approach. I believe I have to do the 3dDeconvolve + 3dLSS 64 times? The code I’m planning to use is as following. Thank you guys so much!
3dDeconvolve -input pb04.$subj.r*.scale+orig.HEAD
-polort A -float
-stim_times_IM 1 img1.txt ‘BLOCK(1, 1)’
-stim_label 1 Image_01
-fout -tout -x1D X.xmat.1D -xjpeg X.jpg
3dLSS -verb -nodata -matrix X.xmat.1D -prefix img1_LSSout -save1D X.LSS.1D
