how to create new ROI: hypothalamus ?

Dear all

I would like to create new ROIs of bilateral hypothalamus (not in the standard atlas tools of CONN) 

according to a research paper
https://doi.org/10.1007/s11695-019-03822-7
and the hypothalamic MRI atlas by Baroncini
LH (x ± 6, y − 9, z − 10 plus 2 mm sphere)
MH (x ± 4, y − 2, z − 12 plus 2 mm sphere)
The coordinates of LH and MH are in standard space (MNI space).


1. can I automatically define this in CONN, or must I pass via e.g. MRICron

2. how to I get it into CONN

3. can I also use these ROIs for 2nd level analyses ROI-ROI ?

THANKS !!
