I'm not sure what you're asking - you should probably take the
appropriate thresh_zstat image from inside the appropriate

avwmaths++

It's up to you. If this isn't clear then you should probably read the
FEAT manual carefully, including the intro to GLM etc stuff in it -
hopfully then it will be clear which is what you want.
