Pre-processing of Single-Cell RNA Data - paired data isn't paired?

Very early on in this tutorial - https://training.galaxyproject.org/training-material/topics/transcriptomics/tutorials/scrna-preprocessing/tutorial.html - I’ve hit an issue. It directs me to select a paired-end dataset collection, but the files it directs me to upload to Galaxy are not paired-end dataset collections and at no point does it direct me to pair them. I can turn them into a paired-end collection, if that’s what it wants me to do, but this should really be clearer in the tutorial, should it not?

Hi @miRlyKayleigh
click at Tip: Importing via link text just under URLs with the files. It describes the upload into a collection. You are correct, I don’t see any relevant description in the main text.
Kind regards,
Igor
