WebDetails filterAndTrim is a multithreaded convenience interface for the fastqFilter and fastqPairedFilter filtering functions. Note that error messages and tracking are not handled gracefully when using the multithreading functionality. If errors arise, it is recommended to re-run without multithreading to troubleshoot the issue. Value delay and repay great western
