    Problem using ANNOVAR for Gene-based annotation

    Hello,

    I am trying to find cancer-specific mutations in the sequenced data.

    I am using Samtools and ANNOVAR as a combination.

    I was able to create a VCF file with variants calling using Samtools.

    Now I am trying to annotate using ANNOVAR. But when I run the command

    " table_annovar.pl vcfinput humandb/ -buildver hg38 -out myanno -remove -protocol cosmic -operation f -xref hg38_cosmic_database.txt"

    I am getting the following eroor
    invalid record found in VCF4 file (at least 8 tab-delimited fields expected):

    I am not able to find how to eliminate this error.

    Can someone please help with it?

    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.
