    Need help in mapping Single end and paired-end reads

    Dear all

    I have in my project single end reads (100 bp) for some samples and paired end reads (100 bp frw and rev) for the other samples. I had to re-sequence some of the samples of which I have paired-end reads because the coverage was to low. However the re-sequence data I received back is single-end reads of 250 bp. Tophat wont allow mapping single and paired-end reads together. It says the result will look bad. They do mention that you can convert the junctions.bed file (output of Tophat) with bed_to_juncs using the -j option. I quote for TopHat manual "run TopHat on the 2nd set of reads using the -j option to supply the junctions file produced by be_to_juncs in the previous step". This is supposed to work but I didn't get it to work. Any suggestion on how I should go about analyzing this data?

    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.
