Hi Regan,
Thanks for the data. It looks possible that the t to z conversion might have precision difficulty for large t-stats.
However the main problem is more simple than that. You have doubled the degrees of freedom in the commands, since the input is specified as:
-setA shellgame_*_belvthink_resampled*
But these files are .HEAD and .BRIK *pairs*. The input should be specified as:
-setA shellgame_*_belvthink_resampled*.HEAD
That will cut the DoF in half, and lead to more reasonable results.
