    rRNASelector error and Metaxa parameters

    Hello
    I'm having trouble to run rRNASelector on unix server through ssh.
    It starts, the dialog box opens on my screen, I choose the reads file (fasta), but then I get this error message:
    "Starting hmmsearch for forward using lib/16s_bact_for3.hmm
    Not right file format! -> Abort"

    My hmmer is ok, when I type hmmsearch -h it gives to me the help information.
    I've tried to run it choosing all possible paths for hmmsearch, but it just crashes. Besides this, the dialog box dynamics is so slow, I cant either change the length parameter...

    In parallel, I'm running Metaxa, and it seems to work well, but for my metagenomic dataset it is finding too few sequences. Is a poor richness dataset, in fact, but even though I was expecting more. My output for bacteria sequences is 61 reads of a total of 110504 sequences. This sequences are from Illumina paired end, merged through Flash, with a average combine of 81% and average length of 293

    The sequences used for rRNASelector are the same
    My goal is to run a diversity workflow in qiime.

    Thanks for every suggestion!!!

    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.
