Index Hopping Metrics File

The index hopping metrics file (Index_Hopping_Counts.csv) contains the number of reads for each expected and hopped index for unique, dual index runs. The count is only reported for UDIs (Unique Dual Indexes) per lane, where no barcode collision is detected in either index. Each pair of entries within each index must have a distance between bases of at least 2n+1, where n is the barcode mismatch tolerance specified for the index, for index hopping metrics to be output for the given lane.

For non-index runs, single index runs, or lanes that do not contain UDIs, the file is output with only the header.
