How to create SQS on other crystal structuers (non cubic)

Alloy Theoretic Automated Toolkit (ATAT)

Is there any page in the manual or forum to build SQS structures beside HCP, cubic, or tetragonal structures?
I would like to make SQS cells for R3 space group, rhombohedral, or triclinic.

Thanks.

Follow the original paper of mcsqs: Redirecting
You can define the lattice parameters of your system at the top.
