How does BUSCO convert MetaEuk identifiers?

Question

[O.rka]

I'm trying to understand the logic of converting the complex MetaEuk identifiers to the more simple identifiers adopted by BUSCO so I can reproduce a manual step for gene calls prior to BUSCO. However, what I thought was the case isn't actually correct. I thought you just get the high and low values.

Both of these (with my incorrect logic) would return the following: NODE_14273_length_2360_cov_2.257701_98:742
