When I tried to run the command I got this error.
libc++abi.dylib: terminating with uncaught exception of type std::domain_error: SystemIsSuspiciuslyFailingTooMuch ctt (maybe your partition is not solvable?)

the input:

and:

Hi @WilliamChristhie,
thanks for the reporting the issue. However, the latest build from the repository works fine there:

$ ./gecmi tests/clsevalsx/gecmi_crash1_n1.cnl tests/clsevalsx/gecmi_crash1_n2.cnl 
0.340984

Probably, you used an older version. I will upload the current build to the "Releases".

Note that the following apps also might be helpful for the clustering evaluations: OvpNMI and xmeasures.

./onmi tests/clsevalsx/gecmi_crash1_n1.cnl tests/clsevalsx/gecmi_crash1_n2.cnl 
# Average estimated membership in 'tests/clsevalsx/gecmi_crash1_n1.cnl': 0.4231 (11 / 26)
# Average estimated membership in 'tests/clsevalsx/gecmi_crash1_n2.cnl': 0.5357 (15 / 28)
0.80563

There is another issue with the gecmi is that I have not normalized the sampling after the speedup optimizations, so it works correctly only to evaluate clusters of approximately the same size. I will fix it, but it is not urgent for me (fixed either since 9c0672 or definitely since the v2.5). I would recommend you to use OvpNMI, where I added also the standard NMI denominator (max divider).

@WilliamChristhie, please look at the latest release v2.50, where all mentioned issues are fixed and some additional features are added.
