    Splitting FASTA files

    Hi all,

    I have a FASTA file which contains protein sequences of a load of genes from D. melanogaster, and need to split the file into multiple FASTAs, one gene per file. What's the best way to go about this? Ideally each file will be named with the name of the gene (UniProt ID).

    Example, the sequence below wants to be split into 2 files, the first called O46197.fasta, the second called Q9VUQ5.fasta

    Many thanks!

    One of these solutions should work.

    I have a huge file with following content: filename: input.txt >chr1 jdlfnhl dh,ndh dnh. dhjl >chr2 dhfl dhl dh;l >chr3 shgl sgl >chr2_random dgld I need to split this file in su...

        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
        by GATTACAT
        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.
