Make output files write-protected

mentioned in commit f7ddc28e

Not all files tagged with protected are made read-only by snakemake. Another one of snakemake's quirks? 😠

Question: Is this a bug in snakemake v6.0.5, which is used in QuaC pipeline? Is it also present in snakemake v5.9.1?

Ran QuaC pipeline with snakemake v5.9.1. It behaved the same way as did v6.0.5. That is, the same selective files that were write protected by v6.0.5 are the only ones write protected by v5.9.1.

Conclusion: Switching to v5.9.1 would not solve the problem.
