Hello,

1. Sparse imaging.

We used sparse imaging to deal with scanner noise so it involved acquisition of brain images after long periods (5-6seconds) of stimulus presentation in the absence of scanner noise. The whole volume was acquired in less then 1 second. TR is 12 seconds.


My question is :

What is the best way to analyze this design with AFNI?

I was using 3dDeconvolve with stim_nptr 1 12 (ideal file was specified in seconds as well) , but I don't know exactly how to specify the min/max lags. Finally I was able to run 3dDeconvolve but i'm not sure that this is the best approach.

thanks again for your help.
