WebFeb 22, 2024 · In commit 6f39ea9, I have made a change to the fastq_mergepairs command. The approach to detect potentially multiple overlap alignments has been changed and now allows many more pairs to be merged. In the ITS1 set, only 56 of 1977 pairs (2.8%) are now rejected. In the ITS2 dataset only 7 of 834 pairs (0.8%) are rejected. ...
