    How to have a library of nucleic acid sequences without going on NCBI

    How to have a library of nucleic acid sequences without going on NCBI every time ?

    Without knowing the full context of this question here are some general suggestions.

    You could keep blast indexes for "nt"(since you asked for nucleic acids) database handy and extract sequences you need using blastdbcmd utility.

    You could also use e-utils from NCBI and fetch data you need (but this can count indirectly as "going on NCBI").

      I wanna check for homology between sequences based on accession numbers and be able to see alignment without going to different websites. Would that be possible with an already made program ?

        You are going to have to visit some websites ....

        If you are working with eukaryotic genes NCBI may have already done the work for you in their homologene project in terms of multiple sequence alignments. Ensembl and UCSC also have similar results available.

        On prokaryotic side you can check this site: http://mbgd.genome.ad.jp/

        If you only have accession numbers then you may need to do some alignments yourself.

          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, detection...

          Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
          by SEQadmin2



          Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

          Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating
