    Help with formating fasta headers

    Hi all,

    I'm fairly new at all of this - trained as a benchtop scientist and learning the bioinformatics on the fly, so sorry if this is a relatively naive question. But I need some help re-formatting fasta headers in a multi-fasta file. I would like to change the headers that look like this:

    >ref|O74455|ID=6PGL_SCHPO|MODRES=|NCBITAXID=284812|Probable 6-phosphogluconolactonase (6PGL)
    MSVYSFSDVSLVAKALGAFVKEKSEASIKRHGVFTLALSGGSLPKVLAEGLAQQRGIEFS

    Into the format for blast2go which is >ref|UniqueID|SeqDescription. So I want the above to look like this:

    >ref|O74455|Probable 6-phosphogluconolactonase (6PGL)
    MSVYSFSDVSLVAKALGAFVKEKSEASIKRHGVFTLALSGGSLPKVLAEGLAQQRGIEFS

    I'm assuming something like sed can do this relatively quickly, I just can't seem to figure out how to remove the fields in-between. Thanks in advance for any help you can offer.

    - Jon

    See if this works.

    Code:
    $ cut -f1,2,6 -d"|" inputfile > outputfile

      fantastic - thank you. I knew there had to be a simple solution.

        Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
        by SEQadmin2



        CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

        Despite this, “CRISPR helped turn genome editing from a specialized technique into

        Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
        by SEQadmin2


        Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

        The systematic characterization of the human proteome has
