Hi Keiran, The -c option clears the duplicate flag and removes any 'dt' or 'do' tags on a read prior to duplicate marking. I added it by request so that a mix of duplicate marking programs did not give inconsistent results. There is no performance advantage, markdup does not take into account

Hi, Can someone clarify the behaviour of "Clear previous duplicate settings and tags" please? If data has been duplicate marked at the "lane" level and then merged and passed into markdup again, should this be in use? Does it give performance advantage by reusing previous information? Thanks
