    Splitting the fasta file into 2 columns

    Hi,

    I have read the fasta file using "read.fasta" from "seqinr" pacakge. The file like like as follows:

    Code:
    >dg_TM_254_2_1
    MASDHAGUWHJAHSHHGAZAGHSGBAHSHGASHJAJAWWQWDSDASJDHKHASK
    ASDASDGASJGZDSGDDHASDHASGD
    >dg_TM_656_2_1
    MJIAKJIEQWIHAASDASJDHASHDKJASDWQOWIOQIWQLAJLSJWIOQUZZEWASD
    >dg_TM_543_1_2
    MUZTREQWERNBVXCYMNMVHZTOPOPOEURDASDOPOQWEUZQUIZRZIRIEIWUEWASDHASHDAHSDHAKHHSDHASHDJASHDAHUWIEUROWUOERUOWEUROOWWWW
    >dg_TM_212_0_2
    MQWUEGSPOZBYCVDVRFTEVWBVRVRVVSDSZTTASDZUZUZUZUADUS
    I would like split the file into the names of the sequence in one column and the corresponding the sequence in another column. I tried like creating data.frame and adding names of fasta_sequences in column and the corresponding sequences in another column, but it failed in R

    Can anyone please guide me.

    Thanks in advance

    Assuming the output of read.fasta() is an object "f"
    Code:
    data.frame(Fragments=names(f), Seqs=unlist(getSequence(f, as.string=T)))

        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.

        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.
