Yah sure. Here is my prim, [prim.json](https://github.com/prisms-center/CASMcode/files/14069498/prim.json) I also wrote, `"filter": "and(eq(comp_n(A), 1), eq(comp_n(B), 3), eq(comp_n(C), 6))"`, but faced same issue.

Then I enumerated by clusters for this settings files, [settings2.json](https://github.com/prisms-center/CASMcode/files/14072137/settings2.json), here I have taken `/1071` because this configuration (which I got when I enumerated this file [settings1.json](https://github.com/prisms-center/CASMcode/files/14072195/settings1.json) contains `A =...

Thank you xivh. Now I totally understood the role of composition axis. Yes firstly I got one configuration of `A =8, B = 24 C = 48` 80 atoms from...

I got 450 configurations of 80 atoms (A = 8, B = 24, C= 48), are you saying me to run DFT calculation of these 450 configurations outside of CASM??...
