  • Trimmomatic: invalid FASTQ name line

    Hi all,

    I'm trying to trim the adapters of my Illumina PE reads using Trimmomatic.

    java -classpath trimmomatic-0.22/old/Trimmomatic-0.20/trimmomatic-0.20.jar org.usadellab.trimmomatic.TrimmomaticPE -phred33 C1_OCT09_tissue_w_larvae/C1_1_s_1_1_sequence.fa C1_OCT09_tissue_w_larvae/C1_2_s_1_2_sequence.fa C1_OCT09_tissue_w_larvae_forward_paired.fq.gz C1_OCT09_tissue_w_larvae_forward_unpaired.fq.gz C1_OCT09_tissue_w_larvae_reverse_paired.fq.gz C1_OCT09_tissue_w_larvae_reverse_unpaired.fq.gz ILLUMINACLIP:IlluminaPE.fa:2:40:15 LEADING:3 TRAILING:3 SLIDINGWINDOW:4:15 MINLEN:20

    And i'm having this problem:

    Exception in thread "main" java.lang.RuntimeException: Invalid FASTQ name line: >ILLUMINA-3AB384_0007:1:1:1011:8817#0/1
    at org.usadellab.trimmomatic.fastq.FastqParser.parseOne(FastqParser.java:45)
    at org.usadellab.trimmomatic.fastq.FastqParser.parse(FastqParser.java:69)
    at org.usadellab.trimmomatic.TrimmomaticPE.process(TrimmomaticPE.java:240)
    at org.usadellab.trimmomatic.TrimmomaticPE.main(TrimmomaticPE.java:338)


    I have no idea how to fix it.
    Some advice???

    Thanks!

    ID lines in fastq files start with an @ symbol, your one starts with an > symbol, like a fasta file.

        If you have your fasta and qual file you can convert to fastq using Galaxy.
        If all you have is fasta and no quality info you can just make a dummy quality line as long as your sequence. Obviously if thats the case you can not trim your sequences by quality.
