Hi all:

After having run 3dDeconvolve and choosing to "bucket" all of the statistical parameters, I find myself in a bit of a bind. I have *way* too many subbricks, and cannot select many of them from the Define Function window. (I have baseline parameters for 9 runs, along with F, t, and Beta coefficients for 36 regressors and 18 glt). I am aware that I can slim down bucket datasets, but as I would like to preserve the names of each sub-brick, I am not sure if this is the best approach. Any recommendations?

A question related to this matter: do I gain any new information by calculating both F and T statistics? In other words, if I merely want to be able to threshold voxels based on p-values, will both statistics suffice equivalently?

Thanks in advance--
Jane Lange
