  • trimmomatic syntax help

    Hi! I am trying to use trimmomatic in palindrome mode to remove adaptor sequence from readthrough past the end of my fragment.
    (My fragments are ~200 nt, and I sequenced with a 2X251 MiSeq run).
    I am having trouble getting the syntax right. Below is command I'm using but I keep just getting a usage message, so I must be typing something in wrong.

    I'm a bench scientist in the process of learning coding by doing, so I'd really appreciate it if anyone could help me spot the noob error. Thanks!


    java -jar `which trimmomatic.jar` /opt/applications/trimmomatic/0.30/trimmomatic.jar
    PE -phred33 -trimlog 092713log1.log
    2013-5_S5_L001_R1_001.fastq 2013-5_S5_L001_R2_001.fastq 092713pairedR1.fastq 092713unpairedR1.fastq
    092713pairedR2.fastq 092713unpariedR2.fastq ILLUMINACLIP:Nexterai7Multiplex2_PE_barcode5.fasta:4:30:7:1:true


    Here's the error I get back. I assume it's the program's way of informing me that I am entering the parameters incorrectly.

    Usage:
    PE [-threads <threads>] [-phred33|-phred64] [-trimlog <trimLogFile>] <inputFile1> <inputFile2> <outputFile1P> <outputFile1U> <outputFile2P> <outputFile2U> <trimmer1>...
    or:
    SE [-threads <threads>] [-phred33|-phred64] [-trimlog <trimLogFile>] <inputFile> <outputFile> <trimmer1>...

    get rid of `which trimmomatic.jar`.... this is a command you use to locate files when you do not know the path.... seeing as this function returns the path, that is what you use

        Current Approaches to Protein Sequencing
        by seqadmin


        Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

        Strategies for Sequencing Challenging Samples
        by seqadmin


        Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
