FounderForge - Prepare Marker Data as AlphaSimR Founder Populations

A point-and-click Shiny application that helps non-programmers prepare their own marker data (VCF, HapMap, numeric genotype matrices or PLINK) as a founder population for AlphaSimR simulations. It guides users through uploading data, quality-control review, filtering (MAF, missingness, monomorphic markers), optional trait definition and export of the objects required by AlphaSimR::newMapPop(), with progress feedback, helpful errors, optional before/after PCA validation and a full text log of the run.
