Dear AFNI experts,

I run two 3dDeconvolve commands, one using a GAMMA function and one using a TENT function (see commands below).

In order to inspect whether the output using the TENT function for a specific condition was consistent with the results computed using a GAMMA function, I’ve uploaded both the -iresp output (underlay) and the stats output (overlay). I'm assuming a coherency between the findings in the two analyses. That is, I’m assuming that for the significant voxels using the GAMMA function, I should get a BOLD response time course that roughly resembles a logarithmic function or a u-inversed shape. This does not seem to be the case (see attached pic).

Could you help with understanding what might be causing the inconsistency?
The text stimfiles for the TENT function consisted of one row per run with the event onsets in seconds. Is this the correct way of setting up the stimfiles?

Thank for your assistance and help!

All the best,
Irene
