Yes, most of the samples were. You don't need live virus in order to sequence.

Which was the problem with all the studies early in 2020 finding SARS-CoV-2 mRNA on surfaces after X hours.

Also the problem with high cycle count rtPCR results long after symptoms have abated.

You can study genomes without ever having to deal with infectious virus, which is vastly simpler.

Whats the point of the extraordinary high levels of bio-security restrictions in these labs then? Wuhan is BSL-4?

The fact that they studied infectious virus in the lab doesn't mean that every sample they studied was infectious virus.
Nobody said that.
