    Seqclean indexing problem

    I downloaded Seqcleanx86_64. I want to remove contaminants from a powdery mildew DNA sequence data using databases I created using makeblast. I use Mac operating system. I tried running the following command line:

    $ Vperl ~/bin/seqclean-x86_64/seqclean LA_Run18_R1.fa -s /Volumes/Data_2/Sandile/raw_data/cont_db/bgh -o LA_Run18_R1clean1 -N -A

    The terminal output recorded the following error:

    Process terminated with an error!
    seqclean (LA_Run18_R1.fa) encountered an error.
    Working directory was /Volumes/Data_2/Sandile/raw_data
    seqclean (LA_Run18_R1.fa) encountered an error.

    I am beginner level at bioinformatics, hence may not have phrased my question properly. Please advise on the probable cause of this error and ways to overcome it.

    I've had the same problem. It's unclear to me if SeqClean can actually run on a Mac - does anybody know this? Since the download appears to be already compiled - I'm assuming it is compiled for Linux and not Mac - hence I've run into the same problems and can't seem to get it to work on my Mac.

      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.
