My RNASeq data appear about 3% adapter contamination and I was trying to trim them using Trimmomatic (v.0.36) but it seems it doesn't work correctly. I got below message a second after I run the program: TrimmomaticPE: Started with arguments:

Then I checked the record DRR091550.2646 HWI-ST886:245:C1T77ACXX:7:1101:17633:2535 and it seems nothing wrong:

@DRR091550.2646 HWI-ST886:245:C1T77ACXX:7:1101:17633:2535 length=101
+DRR091550.2646 HWI-ST886:245:C1T77ACXX:7:1101:17633:2535 length=101

@DRR091550.2646 HWI-ST886:245:C1T77ACXX:7:1101:17633:2535 length=101
+DRR091550.2646 HWI-ST886:245:C1T77ACXX:7:1101:17633:2535 length=101

Does somebody have some suggestions?
