  • Prokka Annotation - How to use blast nr DB

    Hi,

    I want to annotate an assembled Pseudomonas Genome (fasta) with prokka.
    I was successfull so far but I'm not sure where the information comes from.

    I first downloaded a related protein-fasta from NCBI and told prokka to use that file with the --protein option.

    Now what is prokka doing when it finds an unknown cds? Where does it search?

    Is it possible to tell prokka to search in a local downloaded nr blast database?
    maybe it is possible to replace or expand the prokka-used databases by the nr blast db? (I recognized the internal prokka dbs and the nr blast db have different file extensions)

    My idea is:
    Search for all cds in my downloaded, related protein-fasta and at the end to search for all unknown cds in the nr blast database.
    Is that possible?

    Targeted Sequencing: Choosing Between Hybridization Capture and Amplicon Sequencing
    by seqadmin




    Targeted sequencing is an effective way to sequence and analyze specific genomic regions of interest. This method enables researchers to focus their efforts on their desired targets, as opposed to other methods like whole genome sequencing that involve the sequencing of total DNA. Utilizing targeted sequencing is an attractive option for many researchers because it is often faster, more cost-effective, and only generates applicable data. While there are many approaches...

    Expert Advice on Automating Your Library Preparations
    by seqadmin



    Using automation to prepare sequencing libraries isn’t a new concept, and most researchers are aware that there are numerous benefits to automating this process. However, many labs are still hesitant to switch to automation and often believe that it’s not suitable for their lab. To combat these concerns, we’ll cover some of the key advantages, review the most important considerations, and get real-world advice from automation experts to remove any lingering anxieties....
