Hi Lingjie, yes, that issue was on our todo list for a very long time. The occurrence of double hits in paired-end mode with indels is a side effect of overlapping parallelograms of the Swift filter we use in RazerS. In the single-end mode we filter them but in the paired-end it is a bit more involving to detect and correctly filter them. I have found a way this morning which solves the problem easier than I originally thought. Please update to the current trunk of SeqAn and double paired-end hits should be no longer an issue.
