AlloMate also allows to simplify mate allocation by filtering out possible crosses with negative ebvs and by using a kinship threshold between parents set by the user. -Current version calculates kinship through pedigree information only, we are working on supporting genotypic information using an Optimal Contribution Selection (OCS) framework in the near future. +## πŸš€ Features -## Dependencies +### Core Functionality +- **Kinship Analysis**: Calculate and visualize kinship relationships between potential mates +- **EBV Processing**: Combine multiple breeding value traits with user-defined weights +- **Optimum Contribution Selection**: Optimize breeding contributions while controlling inbreeding +- **Mating Plan Generation**: Create optimal mating pairs to minimize inbreeding +- **Excel Export**: Download comprehensive results in Excel format -This app requires the following R packages: +### Technical Features +- **Dual Implementation**: Works with both optiSel package and custom fallback +- **WebR Compatible**: Runs in web browsers without server installation +- **Modular Design**: Clean, organized codebase for easy maintenance +- **Robust Error Handling**: Comprehensive validation and user feedback -- **shiny**: For building the interactive web app interface -- **DT**: For rendering interactive data tables -- **shinyjs**: For additional Shiny JavaScript utilities -- **readxl**: For reading Excel files (if needed) -- **openxlsx**: For writing Excel output files -- **dplyr**: For data manipulation -- **tidyr**: For data tidying -- **readr**: For reading tab-separated files -- **purrr**: For functional programming helpers -- **kinship2**: For pedigree and kinship calculations -- **tibble**: For enhanced data frames +## πŸ“ Project Structure -You can install any missing packages with: +``` +AlloMate/ +β”œβ”€β”€ app/ # Shiny application +β”‚ β”œβ”€β”€ global.R # Shared code (packages, global variables) +β”‚ β”œβ”€β”€ ui.R # User interface code +β”‚ β”œβ”€β”€ server.R # Server logic and reactivity +β”‚ β”œβ”€β”€ R/ # Helper functions and modules +β”‚ β”‚ β”œβ”€β”€ utils.R # Data processing and utility functions +β”‚ β”‚ β”œβ”€β”€ ocs_helpers.R # OCS analysis functions +β”‚ β”‚ β”œβ”€β”€ ui_helpers.R # UI helper functions +β”‚ β”‚ β”œβ”€β”€ load_functions.R # Function loader +β”‚ β”‚ └── optsel_fallback.R # Custom OCS fallback implementation +β”‚ └── www/ # Static resources +β”‚ β”œβ”€β”€ allomate.png +β”‚ └── logos.png +β”œβ”€β”€ scripts/ # Custom implementations and utilities +β”‚ β”œβ”€β”€ optsel_fallback.R # Custom OCS fallback implementation +β”‚ β”œβ”€β”€ validate_ocs_logic.R # OCS logic validation +β”‚ β”œβ”€β”€ compare_ocs_results.R # Results comparison +β”‚ β”œβ”€β”€ ped_ocs_app.R # Pedigree OCS application +β”‚ β”œβ”€β”€ dosage2gmat.R # Dosage to genotype matrix conversion +β”‚ └── test.r # Testing utilities +β”œβ”€β”€ data/ # Sample data files +β”‚ β”œβ”€β”€ candidates_2024_10_29.txt +β”‚ β”œβ”€β”€ pedigree_with_family.txt +β”‚ β”œβ”€β”€ weight_ebvs_for_app_with_family.txt +β”‚ β”œβ”€β”€ length_ebvs_for_app_with_family.txt +β”‚ └── shiny_output.txt # Sample output data +β”œβ”€β”€ AlloMate.Rproj # RStudio project file +└── README.md +``` -```r -install.packages(c("shiny", "DT", "shinyjs", "readxl", "openxlsx", "dplyr", "tidyr", "readr", "purrr", "kinship2", "tibble")) -## Usage +## πŸ› οΈ Installation + +### Prerequisites +- R (version 4.0 or higher) +- Required R packages (automatically installed): + - shiny, readr, dplyr, tidyr, purrr, kinship2, DT, tibble, openxlsx, quadprog + +### Local Installation +1.
