Thank you, Gang.
But we didn't present V* yes-noisy trials, so there are no sub-briks for that.
However, I didn't set up V*yes-noisy contrasts in the glt, why would the 3dMVM won't let it through?
If so, do I have to delete all the V trials since there are only V*no-noisy, but no V*yes-noisy trials?
thanks,
Yue
