On Trimmomatic Error. PE reads

[patriciacl]

Hello!!

I've got 12,438,019 Illumina paired end reads which I'm trying to preprocess in Trimommatic V 0.32 as follows:

java -jar trimmomatic-0.32.jar PE -threads 8 -phred33 -basein /home/DMEL-2/SRR042489_H3_1.fastq -baseout /home/DMEL-2/MOSCAPP ILLUMINACLIP:TruSeq2-PE.fa:2:30:10:true SLIDINGWINDOW:6:10 HEADCROP:10 MINLEN:32

However, I'm getting the below message.
I've not seen this error before. Please advise.

Thanks for your help.

Have you used that version of the Illuminaclip command before?

The error message looks like it's expecting a number instead of the string 'true'.

According to the manual, the command is:
LLUMINACLIP:<fastaWithAdaptersEtc>:<seed mismatches>:<palindrome clip threshold>:<simple clip threshold>:<minAdapterLength>:<keepBothReads>

the default minAdapterLength is 8, so you could try rewriting the command as:

ILLUMINACLIP:./adapters/TruSeq2-PE.fa:2:30:10:8:true

and see if that works.

Hello!!

You're right, it worked.
Thank you.

In regards to the question, I think I've used it before, though it seems than I need to pay more attention to details on PE

Thanks
