    How to do annotation after gene prediction?

    Dear all,

    I am pretty new in bioinformatics. I want to ask, after I perform gene prediction using PRODIGAL, I got the following:


    PHP Code:
    >final_001_R1_00001 # 2 # 898 # 1 # ID=1_1;partial=10;start_type=Edge;rbs_motif=None;rbs_spacer=None;gc_cont=0.644

    GTCGGGATGCTGGTCGGTGCCATCGTGGTGATCGCCGGAATGGGGGAGGACTCGGGTTCG
    TCGGGGTCTTCGTGGGGCATCTACATCGTCATCGGGGTATCGCTGGCCGTCATCGTCGGT
    GCCGTGCCGCTGTTGCTACGTGCCCGCAACACCGCTGCCCAGCGCACCTCGAAAACGGCC

    ACCGCCGCCATCGTCGCGTTCGTCTTCGCCGGGGTGATCACCTGCGCGATGGGGGCCATT
    CCATGGGTGACGCTCAAGAAGCTGCGCGAGCTCGGCTCGTCGGGGTCTTAG 

    After I perform a local BLAST, how can I get something like the following?


    PHP Code:
    >final_001_R1_00001 hypothetical protein
    ATGCCAGCAGGTCGATTGGCCAAGCCACTGGAGGCAATCGCGGGCCCGCTGCGGCGGTCA

    In other words, after performing gene prediction, how to get a file which project the sequences as following?

    PHP Code:
    >gene_0001 GENE_NAME_A
    SEQUENCE
    ...
    >
    gene_0002 GENE_NAME_B
    SEQUENCE
    ...
    >
    gene_0003 GENE_NAME_C
    SEQUENCE
    ...
    >
    gene_0004 GENE_NAME_D
    SEQUENCE
    ...
    >
    gene_0005 GENE_NAME_E
    SEQUENCE
    ...
    >
    gene_0006 GENE_NAME_F
    SEQUENCE
    ...

    Dear garethboy

    I dont't know how to get sequence like that but yes u can use BLAST2GO tool for mapping and annotation. could I know what is your conclusion?

      Use a tool like Prokka (http://www.vicbioinformatics.com/software.prokka.shtml) to predict and annotate your sequences. After the genbank or other files are generated, write a script to add the annotation to your fastA file.

        Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
        by SEQadmin2



        Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

        Cancer Drug Resistance: The Lingering Barrier to Rising Survival
        by SEQadmin2



        Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

        There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

        Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing

        Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
