Which means filtering quality before pair-end merge, might be useful for gene with length heterogeneity, or libraries with low quality at 3'-end
For TRUNCLEN == "no" and QFILT == "maxee", filtration is only done after pair-end merge.
For TRUNCLEN == "xx" and QFILT == "maxee", filtration is done before pair-end merge, and optimization
Introduce TRUNCBE: Truncation before pair-end
