CAMISIM hybrid time series data
<p>CAMISIM was used to simulate Illumina and Nanopore reads for a time series based on the genome sources from the “CAMI II challenge toy mouse gut dataset” (Meyer et al., 2021), containing 791 genomes. For this, the most recent development version of CAMISIM at the time of preparing this data was used (available at <a href="https://doi.org/10.5281/zenodo.5137751">https://doi.org/10.5281/zenodo.5137751</a>). Two groups of samples were generated by using different CAMISIM seeds, each comprising a time series of four samples.</p> <p>The sample sheet file (samplesheet.CAMISIM_hybrid.csv) can be used as direct input for the nf-core/mag pipeline, e.g. with the command:</p> <p>> nextflow run nf-core/mag -r 2.1.0 -profile <docker/singularity/podman/shifter/charliecloud/conda/institute> --input https://zenodo.org/record/5155395/files/samplesheet.CAMISIM_hybrid.csv --coassemble_group</p> <p>Note, in case of download problems, restarting the pipeline run with `-resume` or downloading the files beforehand and adjusting the paths in the sample sheet file should help.</p> <p>See <a href="https://nf-co.re/mag">https://nf-co.re/mag</a> for a comprehensive usage documentation.</p> <p> </p>
"Genome binning of viral entities from bulk metagenomics data" - CAMISIM simulated datasets and genomes

To this end we generated 3 different metagenome compositions with up to 308 reference genomes; one mixed with bacteria, plasmids and viruses to test binning in complex samples i.e. high diversity (1), one with only crass-like viruses to test binning with highly similar viruses i.e. high relatedness (2) and a set of small-viruses (<6,000 bp) including members of the Microviridae family to address the bias of size (3). Bacterial genomes were gathered from NCBIs refseq genome repository 2021, plasmids from the PLSDB database (v. 2021_06_23) and viral genomes from the recent MGV database. </p> <p>Dataset A contained a mixture of bacteria (N=8), plasmids (N=20) and viruses (N=280) to test binning in complex samples, i.e. high diversity. Dataset B contained only crass-like viruses (N=80) to test binning with highly similar viruses i.e. high relatedness. Dataset C contained small-viruses (N=50, <6,000 bp) of the Microviridae family to address the bias of size. Bacterial genomes were sampled from the Refseq genome repository 2021, plasmids from the PLSDB database and viral genomes from the recent MGV database (Nayfach, et al. Nature Microbiology 2021).</p> <p> </p> <p> </p>
CAMISIM Default Nanopore Community
<p>Dataset generated with CAMISIM, using the mini_config.ini on Dec 20, 2020. The read simulator was swapped for NanoSim (<a href="https://github.com/abremges/NanoSim">https://github.com/abremges/NanoSim</a>), and the output set to 0.1Gb.</p>
