VIEWpoly (V 0.4.1): A Shiny App to Visualize Genetic Maps and QTL Analysis in Polyploid Species

VIEWpoly is a shiny app and R package for visualizing and exploring results from polyploid computational tools using an interactive graphical user interface. The package allows users to directly upload output files from polymapR, MAPpoly , OneMap, polyqtlR, QTLpoly, diaQTL, GWASpoly, HIDECAN, and genomic assembly, variants, annotation and alignment files. VIEWpoly uses shiny, golem, ggplot2, plotly, and JBrowseR libraries to graphically display the QTL profiles, positions, alleles estimated effects, progeny individuals containing specific haplotypes and their breeding values. It is also possible to access marker dosage and parental phase from the linkage map. If genomic information is available, the corresponding QTL positions are interactively explored using JBrowseR interface, allowing the search for candidate genes. It also provides features to download specific information into comprehensive tables and images for further analysis and presentation.
