After the latest commit on the master branch I get the following error

./qflex.x 11 12 2 0.005 ./circuits/ben_11_16_0.txt ./ordering/bristlecone_48.txt ./grid/bristlecone_48.txt
The number of qubits read from the file: 70, does not match I*J: 132.

The circuit file "ben_11_16_0.txt" assumes that you're using bristlecone_70 (thus the "70" at the top of the file). You'll need to use the corresponding ordering and grid files to run that circuit.

This behavior is intentional - the only reason this invocation worked before is because we were silently ignoring bad gates in the input. We'll need to update the relevant examples before resolving this issue.

i did not look at the file names...my bad...
