Hello Rhiannon,
Is there an easy way to get LVC_NR format waveforms from an ETK simulation directory?

"export numerical relativity data to the format required for LIGO analyses"
will probably do the trick. There may be others (not sure about kuibit or a public version of SimulationTools), but MayaWaves may be a good start.
Yours, Roland
