    Metamos help request

    Has anyone out there used MetAmos with a single read fastq file? I've downloaded the binary with Blast DBs and tried using initPipeline -q -1 myfile.fastq which seems to work, but then when I do runPipeline it errors out at the MapReads step with Bowtie2 giving an error that sounds like it's looking for paired data. Am I missing a parameter somewhere?

    I believe (could be wrong) you're looking for -m. From the man:

    -m: interleaved file of paired reads
    usage: initPipeline -q -m file.fastq.12 -d projectDir -i 300:500

      I'm using single reads, so the -m is for specifying mate-paired reads, and the -i parameter is for insert size - I can't give an insert size as that only applies to paired reads... right?

      I believe my problem has to do with the binary download. I have had *slightly* more luck getting some of the pipeline running with the version 1.3 download, but there are several parts of the pipeline that I cannot get installed and working on my system (Ubuntu 12.04), with Glimmer-MG, Kraken and MetaPhyler all giving me fits, never installing all the way. It seems like to get a lot of this working right you have to be an expert in ALL of the languages used... shell scripting, R, Perl, Python, java, c++.

        Are you using the precompiled binary?

          I started off using the binary, but as I mentioned, it seems like it's looking for paired data exclusively, so I switched to using 1.3 (non-binary) version. I am still having trouble getting the whole pipeline to work, but making progress.

            Ah, I see now you mentioned that. I've been trying off and on with folks to get the 1.2 binary to work, but it has had several problems, including the one you mentioned. The most recent was that it was referencing a path that didn't exist.

            Anyway, I've been a little out of the loop the last few weeks, but I see that a 1.3 frozen binary is now available. This at least will make your set up a little easier...

              Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
              by SEQadmin2



              CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

              Despite this, “CRISPR helped turn genome editing from a specialized technique into

              Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
              by SEQadmin2


              Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

              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.
