  • Blastn Results - analysis

    Hi Everyone,

    I have done some blasting on a draft genome that I assembled de novo(~300,000 contigs) and now I want to analyze the results. I used blastn, and I really want to see what was found in the blast results. Blast2GO doesn't help with this (I believe its because I didn't blastx or blastp)

    SO, my question is, can anyone give me an idea on what program I can use to manipulate/analyze the results so that I can look at the stats of the top hits, etc?
    My blastn results are in tabular format. Any ideas will be extremely helpful.

    Thank you!

    Correct, Blast2GO wants either BLASP or BLASTX against the NR protein database.

      What kind of stats? If you just want the top hit, you can tell BLAST to only give you one hit per query.

        The kind of summary stats I am aiming for or rather looking to extract is kinda similar of what is outputted by blast2go, ie in terms of top hit species and species distribution.
        So, I was wondering if there is any other program out there that I can feed the BlastN results to get the stats. Or if anyone has a script to share that I can use to manipulate the data and extract such results.

          BLAST 2.2.28+ or later has the option of outputting the species name in the tabular output:

            A Brief Overview and Common Challenges in Single-cell Sequencing Analysis
            by seqadmin


            ​​​​​​The introduction of single-cell sequencing has advanced the ability to study cell-to-cell heterogeneity. Its use has improved our understanding of somatic mutations1, cell lineages2, cellular diversity and regulation3, and development in multicellular organisms4. Single-cell sequencing encompasses hundreds of techniques with different approaches to studying the genomes, transcriptomes, epigenomes, and other omics of individual cells. The analysis of single-cell sequencing data i...

            by seqadmin
            Single-cell sequencing is a technique used to investigate the genome, transcriptome, epigenome, and other omics of individual cells using high-throughput sequencing. This technology has provided many scientific breakthroughs and continues to be applied across many fields, including microbiology, oncology, immunology, neurobiology, precision medicine, and stem cell research.

            The advancement of single-cell sequencing began in 2009 when Tang et al. investigated the single-cell transcriptomes
