That's not a very clear error message, huh @Alejandra_Szabo? Sorry about that!
It looks like you've misspelled the semantic type in your command. Compare:
Good: MultiplexedSingleEndBarcodeInSequence
Bad: MultiplexedSingledEndBarcodeInSequence
This error has popped up before on the forum (1, 2, 3), and I figured out how to solve it by searching for part of the error message: 'compatible directory format'. The forum's search feature (at the top right hand corner) is often much faster than posting and waiting for a response, and I'd encourage you to give it a shot next time you run into an issue like this.
Thanks for your patience, and good luck!
