    error running STAR

    I am using STAR to map my paired end rna seq data. I keep running into the following error msg.
    EXITING because of FATAL ERROR in input reads: unknown file format: the read ID should start with @ or >
    This was my command line:
    -bash-3.2$ /pathToStarDir/ STAR --genomeDir /pathToGenome/ --readFilesCommand zcat --readFilesIn /pathToFile/587352_1_1.fastq.gz pathToFile/587352_1_2.fastq.gz --runThreadN 3

    When I zless my .fastq.gz file to check the format of the file, the first few lines looks like this:

    Has anyone ran into similar problems before? Is it a file problem or there was mistakes in my command ?

    Thanks for the help in advance.

    Can you try Brian's repair.sh tool to see if you can fix problems with your fastq files: http://seqanswers.com/forums/showpos...0&postcount=45 I am not sure if it will catch malformed ID headers.

    Alternatively fastqValidator can be used to see if you do have a problem with formatting: http://genome.sph.umich.edu/wiki/FastQValidator

      I don't see a problem with the first 8 lines, at least. And yes, repair.sh requires correctly-formatted fastq headers; it's only for fixing broken pair ordering. I'm not familiar with how STAR deals with gzipped files, but perhaps you could try decompressing it first?

        The part about this topic feels surprisingly grounded, and the details on the page is the bit that made me slow down. I’d keep <a href="https://kinpict.com/">ai family photo generator</a> bookmarked for later.

        16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
        by SEQadmin2





        NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification,...
