  • Comparing bacterial genomes

    Hi everybody,
    I am beginner in the field of bacterial genomics and bioinformatics, and I have 8 de novo assembled bacterial genomes and 2 ref. genomes from NCBI. I would like compare all the 10 genomes against each other to to detect the unique sequence fragments (or genes) that are present only in my genomes, also the similarities to the ref. genomes.

    I hope that someone could help me with suggestions on how I could do so and which tool(s) or scripts are available for this purpose.


    Thank you so much in advance

    Try Mauve: http://darlinglab.org/mauve/mauve.html

      If you want to focus on genes, you can try blast methods such as bidirectional best hit, OMCL, etc. several software can do this. I used Get_homologues and it worked well.

        GenoMax and yzzhang, Thank you so much for your prompt reply.
        Indeed, I was algined my genomes using Mauve, but I could only check it manually.
        Is there a way to export the differences as fasta file or table with start and end positions?

        Thank you so much

            Current Approaches to Protein Sequencing
            by seqadmin


            Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

            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...
