External Email - Use Caution        

I can't remember why I removed it, but there was some problem with it. You can do the conjunction with
mri_concat contrast1/sig.nii.gz contrast2/sig.nii.gz --min --o conjunction.nii.gz
You can have as many contrasts as you want
This will do an "AND" conjunction
If you want an "OR" conjunction, then use --max instead of --min

Dear experts,

Another question: How do I do conjunction analysis? I have my contrasts on 1lvl, I have the second level, I need a conjunction of two contrasts.

I would guess "mergecontrasts-sess", unfortunately, it doesn't seem to work.

Could you help me with that issue?
Kind regards,
