    Extracting probe id's

    I have downloaded some CEL files from GEO, and wish to annotate probe id's with AILUN. Can someone advise me about the most time-efficient way of extracting the probe id's from the CEL files? Is there for example some grep command that could do the job? I'm unfortunately not familiar enough with UNIX to figure this out..

    I assume that if you have .CEL files the data is from Affymetrix arrays.

    Have a look at the Affymetrix website

    Download annotation files to understand what biological entities are represented on Applied Biosystems GeneChip arrays.


    as well as the Bioconductor website and mailing lists.

    The Bioconductor project aims to develop and share open source software for precise and repeatable analysis of biological data. We foster an inclusive and collaborative community of developers and data scientists.


    Affymetrix usually releases annotations for their arrays. Even if you want to do your own annotations, the Affymetrix files are csv text files, which you can open in Excel, and the first column in the files is usually the probe set identifiers.

        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

        Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
        by SEQadmin2



        Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.
