Efficient and Low-Cost Construction of Synthetic Communities R package syncons version 0.1.1 Provides functions and a Shiny application to design plate layouts for constructing synthetic communities (SynComs) from a pool of strains using 24-, 96- and 384-well microplates. The method generates all possible strain combinations in a scalable, low-cost workflow suitable for high-throughput experiments. Reference: Tian et al. (2024) <doi:10.21769/BioProtoc.2405576>.
