Hi there,
I am currently using the most recent version of AFNI and I am running the deconvolution script which is attached. cat_TS stands for the concatenated timeseries which is unsmoothed. Also there are four runs . When I look into the resulting bucket I see no sub-bricks for any of the baseline parameters which I did include with polort 2. Also what is strange is that the IRFs are different--it appears that the baseline may have not been removed but I don't know. What do you think is wrong if anything and if not wrong can you explain these differences between old files and that of the new version of AFNI. I am trying to use the statistics obtained from the deconvolution to do an FDR analysis and I am worried that the deconvolution results may be wrong. I would greatly appreciate any info you have on this. Like is my "old" way of doing the event-related design obsolete?
thanks much.
