Hi,my hisat2 run of paired reads resulted in the following report:

24615923 reads; of these: 24615923 (100.00%) were paired; of these: 9554401 (38.81%) aligned concordantly 0 times 11086995 (45.04%) aligned concordantly exactly 1 time 3974527 (16.15%) aligned concordantly >1 times

9554401 pairs aligned concordantly 0 times; of these: 4616966 (48.32%) aligned discordantly 1 time

4937435 pairs aligned 0 times concordantly or discordantly; of these: 9874870 mates make up the pairs; of these: 3846849 (38.96%) aligned 0 times 3981801 (40.32%) aligned exactly 1 time 2046220 (20.72%) aligned >1 times 92.19% overall alignment rate

There are quite a bit of reads aligned discordantly 1 time.
So i wonder is this mapping rate OK?

Thank you!
