ggrepel is an R package that provides geoms for ggplot2 to repel overlapping text labels:

  • geom_text_repel()
  • geom_label_repel()

Text labels repel away from each other, away from data points, and away from edges of the plotting area.

library(ggrepel)
ggplot(mtcars, aes(wt, mpg, label = rownames(mtcars))) +
 geom_text_repel() +
 geom_point(color = 'red') +
 theme_classic(base_size = 16)

SNPSEA

GitHub

SNPSEA is a SNP Set Enrichment Algorithm to identify which cell types preferentially express the genes that are associated with a trait.

Input files:
  1. A list of genome-wide significant SNP identifiers (e.g. rs42) from a genome-wide association study (GWAS) on your preferred trait.
  2. A (NxM) matrix of gene expression values for all genes (N) across a large number (M) of cell types.

Figure 1

SNPSEA compares the trait-associated single-nucleotide polymorphisms (SNPs) to randomly sampled SNPs while accounting for linkage disequilibrium (LD). It's implemented in C++ with executables available for macOS or Linux.

Just for Fun

snpbook

GitHub View

Find proxies for your favorite single nucleotide polymorphism (SNP). This is a simple HTML and Javascript page that uses some tricks to query the variants in the 1000 Genomes Project and compute linkage disequilibrium (LD) in the web browser.
