#2092 test: add explicit lane column to multi-run samplesheets Pull request opened by znorgaard Working on implementing the suggestion from @clintval here: nf-core/fastquorum#147 (comment) Notable, this breaks backwards compatibility, but arguably makes it so people can't do the wrong thing on accident (accidental sample duplication -> accidental merge). The fastquorum pipeline will not auto-assign lane numbers for samples or libraries with multiple runs; each run must be identified by an explicit lane and/or flowcell. This PR adds a lane column to the multi-run samplesheets so they remain valid inputs. nf-core/test-datasets
