## gSpreadComp: Streamlining Microbial Community Analysis for Resistance, Virulence, and Plasmid-Mediated Spread

### Overview gSpreadComp is a UNIX-based, modular bioinformatics toolkit designed to streamline comparative genomics for analyzing microbial communities. It integrates genome annotation, gene spread calculation, plasmid-mediated horizontal gene transfer (HGT) detection and resistance-virulence ranking within the analysed microbial community to help researchers identify potential resistance-virulence hotspots in complex microbial datasets. > [!TIP] > After installation, the user may want to check a detailed tutorial with example input and output data [here](usage_tutorial.md) ### Objectives and Features - **Six Integrated Modules**: Offers modules for taxonomy assignment, genome quality estimation, ARG annotation, plasmid/chromosome classification, virulence factor annotation, and in-depth downstream analysis, including target-based gene spread analysis and prokaryotic resistance-virulence ranking. - **Weighted Average Prevalence (WAP)**: Employs WAP for calculating the spread of target genes at different taxonomical levels or target groups, enabling refined analyses and interpretations of microbial communities. - **Reference Pathogen Identification**: Compares genomes to the NCBI pathogens database to create a resistance-virulence ranking within the community. - **HTML Reporting**: Culminates in a structured HTML report after the complete downstream analysis, providing users with an overview of the results. ### Modular Approach and Flexibility `gSpreadComp`’s modular nature enables researchers to use the tool's main analysis and report generation steps independently or to integrate only specific pieces of `gSpreadComp` into their pipelines, providing flexibility and accommodating the varying software management needs of investigators. #### Using other annotation tools with gSpreadComp > [!TIP] > Users can incorporate results from other annotation tools within gSpreadComp's workflow, provided the input is formatted according to gSpreadComp's specifications. This allows for the integration of preferred or specialized tools for specific steps (e.g., alternative ARG or plasmid detection methods) while still benefiting from gSpreadComp's downstream analysis capabilities. > > For the quality data it should look like: [Quality DataFrame Format](test_data/checkm_df_format_gSpread.csv) > > For the taxonomy data it should look like: [Taxonomy DataFrame Format](test_data/gtdb_df_format_gSpread.csv) > > For the gene annotation (e.g. ARGs) data it should look like: [Gene annotation DataFrame Format](test_data/deeparg_df_format_gSpread.csv) > > For the plasmid identification data it should look like: [Plasmid identification DataFrame Format](test_data/plasflow_combined_format_gSpread.csv) > > Metadata information data should look like: [Metadata Sample](test_data/02_metadata_gspread_sample.csv) By the end of a successful run, you should have a report that looks like this: [Download Example Report](https://raw.githubusercontent.com/mdsufz/gSpreadComp/refs/heads/main/test_data/gSpread_example_result_report.html) ### Comprehensive Workflow ![ScreenShot](/test_data/01_Kasmanas_gSpread_Fig_1.png) gSpreadComp consists of the following modules: 1. **Taxonomy Assignment**: Uses [GTDBtk v2](https://academic.oup.com/bioinformatics/article/38/23/5315/6758240) for taxonomic classification. 2. **Genome Quality Estimation**: Employs [CheckM](https://genome.cshlp.org/content/25/7/1043) for assessing genome completeness and contamination. 3. **ARG Annotation**: Utilizes [DeepARG](https://microbiomejournal.biomedcentral.com/articles/10.1186/s40168-018-0401-z) for antimicrobial resistance gene prediction. 4. **Plasmid Classification**: Implements [Plasflow](https://academic.oup.com/nar/article/46/6/e35/4807335) for plasmid sequence identification. 5. **Virulence Factor Annotation**: Annotates virulence factors using the [Victors](https://academic.oup.com/nar/article/47/D1/D693/5144967?login=false) and/or [VFDB](http://www.mgc.ac.cn/VFs/main.htm) databases. 6. **Downstream Analysis**: Performs gene spread analysis, resistance-virulence ranking, and potential plasmid-mediated HGT detection. # Requirements Before installing and running `gSpreadComp`, ensure that your system meets the following requirements: ## 1. Operating System - Linux x64 system ## 2. Package Managers - [Miniconda](https://docs.conda.io/en/latest/miniconda.html): Required for creating environments and managing packages. - [Mamba](https://mamba.readthedocs.io/en/latest/user_guide/mamba.html): A faster package manager used within the `gSpreadComp` installation. ## 3. Storage - Approximately 15 GB for software installation. - Around 92 GB for the entire database requirements. # Installation ## Database Management `gSpreadComp` includes an easy-to-use script for automatic download and configuration of the required databases, with scheduled updates every January and July. ## Compatibility and Requirements Designed to support Linux x64 systems, requiring approximately 15 GB for software installation and around 92 GB for the entire database requirements. ## 1 - Install miniconda To bypass conflicting dependencies, the gSpreadComp approach uses miniconda to create automatically orchestrated environments. [Mamba](https://mamba.readthedocs.io/en/latest/user_guide/mamba.html) is a much faster package manager than conda and is used within the gSpreadComp installation. Consequently, miniconda and mamba are required to be previously installed in your system. Below is a possible way of installing miniconda and mamba. Please, be aware that mamba works best when installed in your base environment. ```console # See documentation: https://docs.conda.io/en/latest/miniconda.html $ wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh $ chmod +x Miniconda3-latest-Linux-x86_64.sh $ ./Miniconda3-latest-Linux-x86_64.sh $ export PATH=~/miniconda3/bin:$PATH # Install mamba. See documentation: https://mamba.readthedocs.io/en/latest/installation.html $ conda install mamba -n base -c conda-forge ``` ## 2 - Install gSpreadComp Once you have miniconda and mamba installed and on your PATH, you can proceed to install gSpreadComp. The installation script was designed to install and set up all necessary tools and packages. ```console # Clone repository $ git clone https://github.com/mdsufz/gSpreadComp.git # Go to the gSpreadComp cloned repository folder $ cd gSpreadComp # Make sure you have conda ready and that you are in your base environment. $ conda activate base $ echo $CONDA_PREFIX # You should see something like the following: /path/to/miniconda3 # Run the installation script as follows $ bash -i installation/install.sh # Follow the instructions on the screen: # Enter "y" if you want to install all modules; otherwise, enter "n". # If you entered "n", enter "y" for each of the modules you would like to install individually. The MuDoGeR's installation will begin.. ( ) ( ) ) ) ( ) ( ( ( ) ( ) ) _____________ <_____________> ___ | |/ _ \ | | | | | |_| | ___| |\___/ / \___________/ \ \_____________________/ This might take a while. Time to grab a coffee... ``` ## 3 - Install necessary databases **Make sure to run the database setup after gSpreadComp is installed.** Some bioinformatics tools used within gSpreadComp require specific databases to work. We developed a database download and set up tool to make our lives easier. You can choose to install only the databases you intend to use. You can use the flag `--dbs` to choose and set up the selected databases (all [default], install all databases). Use this script if you want gSpreadComp to take care of everything. ```console # Make sure gSpreadComp_env is activated. It should have been created when you ran 'bash -i installation/install.sh' $ conda activate gspreadcomp_env # Go to gSpreadComp cloned directory $ cd gSpreadComp # Run the database setup script $ bash -i installation/database-setup.sh --dbs all -o /path/to/save/databases # You can also check out the database-setup help information $ bash -i installation/database-setup.sh --help gSpreadComp database script v=1.0 Usage: bash -i database-setup.sh --dbs [module] -o output_folder_for_dbs USE THE SAME DATABASE LOCATION OUTPUT FOLDER FOR ALL DATABASES USED WITH gSpreadComp --dbs all download and install the required and optional databases [default]" --dbs required download and install the required databases (Victors and VFDB) for gSpreadComp --dbs optional download and install all the optional (ARGs, GTDB-tk, CheckM) databases for gSpreadComp --dbs args download and install the required and the ARGs databases. -o path/folder/to/save/dbs output folder where you want to save the downloaded databases --help | -h show this help message --version | -v show database install script version ``` ## Usage ### Activating the Conda Environment Before using `gSpreadComp`, activate the appropriate conda environment using the following command: ```sh conda activate gSpreadComp_env ``` ### Command-Line Usage `gSpreadComp` provides several modules, each performing a specific task within the pipeline.
