Dear Ken,

in the current SDM software, you should include a filter variable for group B and a filter variable for group C. After running the analyses, you will have:

- XXX_00: group A
- XXX_10: group B
- XXX_01: group C
- XXX_10m00: group B vs group A
- XXX_01m00: group C vs group A
- XXX_10m01: group B vs group C

With the best regards,

Joaquim
