An error message while generating sqscell.out file

Hi:

I want to use ATAT to generate an alloy model with 60 atoms by the input rndstr.in file and the clusters.out file.

I use mcsqs -2=5 to generate the clusters.out file first.

However, when I type mcsqs -n=60 to generate the supercell.out file, an error message appears," Impossible to match point correlations due to incompatible supercell size."

I have looked other people’s sismilar post, and I learn that maybe the problem is my model size is too small. Then, I increase my scale upon the alloy model with 200 atoms, and then it can work.

Can anyone tell me, how can I do if I want to generate a smaller alloy model like 60 atoms or 80 atoms? I think 200 atoms model is too big for me to run with only 32 cores supercomputer.

Thank you.

The input rndstr.in is as follows:
