    Trimmomatic problem

    Hi,

    i'm trying to run trimmomatic in pair-ended mode on my two fastq file, but it doesn't work without any error message. Here is what i'm running

    Code:
    java -jar trimmomatic-0.32.jar PE -phred33 input1.fast input2.fast pair1.fastq unpair1.fastq pair2.fastq unpaire2.fastq
    When I do that it just said :

    Code:
    Usage: 
           PE [-threads <threads>] [-phred33|-phred64] [-trimlog <trimLogFile>] [-basein <inputBase> | <inputFile1> <inputFile2>] [-baseout <outputBase> | <outputFile1P> <outputFile1U> <outputFile2P> <outputFile2U>] <trimmer1>...
       or: 
           SE [-threads <threads>] [-phred33|-phred64] [-trimlog <trimLogFile>] <inputFile> <outputFile> <trimmer1>...
    I tried to change different things, but nothing seems to work. I tried the "classpath" method which does the exact same thing.

    Hope you can help ! thanks

    I think the relevant part of the Usage error message that applies to the code you showed is

    '<trimmer1>'.


    You need to specify what trimming operations you want trimmomatic to do.
    See the trimmomatic web page and the manual for a list of options.

      Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

      Nine Things a Sample Prep Scientist Thinks About Before Sequencing

      I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

      Here are nine questions we think about, in roughly the order they matter, before...
