... Hello everyone, I have Illumina paired end (2*150bp) reads for 30 samples that I mapped to the reference genome using Tophat2. The sequencing providers gave me the following information: - The fragments used for sequencing range from 200 to 400bp - The average size is around 303 to 330bp. This inc ...

Trimmomatic : keepBothReads True vs False option
... Hello everyone, Is anyone familiar with the **"keepBothReads"** in **Trimmomatic** : **keepBothReads:** After read-through has been detected by palindrome mode, and the adapter sequence removed, the reverse read contains the same sequence information as the forward read, albeit in reverse complem ...

Comment: C: Trimmomatic adapter file TruSeq3-PE-2.fa
... Oh I see! But did you check your R1 and R2 files for the presence of the adapters mentioned by Illumina. My only issue is the sequence mentioned in the trimmomatic adapter file as 2 is actually for R1 and vice versa. ...

Comment: C: Trimmomatic adapter file TruSeq3-PE-2.fa
... Hi Macspider, Could you please share the adapter file you used for removing adapters from Truseq PE data using Trimmomatic. Was your file similar to mine or did you use the "TruSeq3-PE-2.fa". Though the sequences and their reverse complements are the same, but if you notice, they are for opposite ...

Comment: C: Trimmomatic adapter file TruSeq3-PE-2.fa
... Yes it is also mentioned in the manual that one needs to mention the reverse complement. My doubt is regarding the universal usage of the Trimmomatic provided adapter file "TruSeq3-PE-2.fa". Should this file be used always? Or was I right in making my own file according to the adapters in my file. ...
