![]() Additional Autometa options īy enabling taxonomy aware mode, Autometa will attempt to use taxonomic data to make your bins more accurate. Not particularly great (the N50 is 1100bp). In the example below, I have chosen a cutoff of 1000bp as my assembly was I would strongly recommendĪgainst choosing a number below 900 here. If your N50 is more along the lines of 5000, I would leave the cutoff at the default 3000. if your N50 is 1200bp, I would choose a cutoff of 1000. This cutoff will depend on how good your assembly is: e.g. To select the latest version, ensure that the double, right-handed arrows are next to 2.0.0, then hit “Enter”. The latest version of the tool will always be at the top of the list with older versions descending below. The double, right-handed arrows should already indicate the latest release of Autometa (in our case 2.0.0). KwanLab/Autometa nf-core parameter settings:ĭo you want to run the nextflow command now? You will now use the arrow keys to move up and down between your options and hit your “Enter” or “Return” key to make your choice. It is much easier (and less error prone) to copy/paste the sample sheet file path when specifying the input (We’ll get to this later in Input and Output). You may want to note where you have saved your input sample sheet prior to running the launch command. You can activate your environment by running: If you used a different assembler you will need to provide either raw reads or a table containing contig/scaffold coverage information.įull details for data preparation may be found under Preparing a Sample Sheetįirst ensure that your Autometa conda environment is activated. If the metagenome was assembled via SPAdes, Autometa can extract coverage and contig length information from the sequence headers. Where that data is found and how to retrieve the sample’s contig coverage information. Want to process, you will need to provide a sample sheet which specifies the name of your sample, the full path to Regardless of the number of metagenomes you □ □ Running Autometa įor a comprehensive list of features and options and how to use them please see Running the pipelineĪutometa can bin one or several metagenomic datasets in one run. Save your new file with Ctrl+O and then exit nano with Ctrl+O. For the sake of this example I will be keeping it in a folder called “Useful scripts” in my home directoryīecause that is a central point for me where I know I can easily find the file and it won’t be moved e.g. Process.queue = "agrp" // <<- change this to whatever your partition is called We usually use metaQuast for this (use -min-contig 1 option to get an accurate N50). We usually use MetaSPAdes which is a part of the SPAdes package.Ĭheck the quality of your assembly (Optional) Quality check the trimmed reads to ensure the adapters have been removed The following is a typical workflow for metagenome assembly: You will first need to assemble your shotgun metagenome, to provide to Autometa as input. Nextflow (required) and nf-core tools (optional but highly recommended) installation will be discussed in Installing Nextflow and nf-core tools with Conda. Detailed system requirementsĬan be found in the nextflow documentation ![]() Nextflow runs on any Posix compatible system. We plan on removing this dependency in future versions, so that other dependency managers If you don’t have Docker installed you can install it from /get-docker. System Requirements Ĭurrently the nextflow pipeline requires Docker □ so it must be installed on your system. Nextflow helps Autometa produce reproducible results while allowing the pipeline to scale across different platforms and hardware. □ Nextflow Workflow □ Why nextflow?
