  • Select Single-copy genes from a newick format file

    Hi everyone,

    I have a large orthologous tree file (newick format) with one tree per line. I only want the single-copy gene trees (one copy per one species). I tried to select by the ID of the species with awk command but I always modified and damaged the trees.

    The simplest tree is like ("(", ID of the species 1, dot, name of the gene, ":", distance value, ID of the species 2, dot, name of the gene, ":", distance value, ")", ";" ):

    (ID1_XXXX.geneXXX:0.XX,ID2_XXXX.geneXXX:0.XX);

    Any script/idea to select the single-copy gene trees?

    Strategies for Sequencing Challenging Samples
    by seqadmin


    Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
