Shiny Apps

This R Shiny app clusters samples based on their genotype data across a set of markers and creates MDS, tree, and tile plots.

Sample data files can be found at:

https://github.com/mfcovington/shiny-cluster-genotypes/releases/tag/sample-files.

One sample file is tab-delimited and the other is comma-separated. In the file named 'sample-data.snps.txt', both 'N' and 'U' represent NA values. Therefore, enter the following into the field for NA strings: N,U

QTLvizR is a web application to help visualize quantitative trait loci (QTL).

This app allows the user to select physiological and developmental traits from a drop down menu. The app displays the support for a physiological or developmental (pQTL) for every genotyped marker across the organism's genome.

The user can sub-select specific chromosomes, or intervals along a chromosome to focus attention on. At the same time, QTL's for gene expression (eQTL) for genes falling within the user defined genomic interval are also visualized. This allows the user to quickly examine a genomic region for co-occurrence of pQTL and eQTL.
