This package provides the output of running Salmon on a set of 24 RNA-seq samples from Alasoo, et al. “Shared genetic effects on chromatin and gene expression indicate a role for enhancer priming in immune response”, published in Nature Genetics, January 2018 doi: 10.1038/s41588-018-0046-7.
6 donors were selected from those that had publicly available reads in
ENA. The selection procress is recorded in the file
inst/scripts/ena_download.R, the donors were chosen as all female,
the sample having been received as frozen, and then the top 6 were
chosen based on mean purity as recorded by the study authors.
Salmon
version 0.12.0 was run using
Gencode
human reference transcripts v29, with a
snakemake
script that can be seen in inst/scripts/Snakemake and with
log output in inst/scripts/snakemake.log.
The quantification output is in the inst/extdata/quant
directory. The quant.sf files have been gzipped to preserve space,
so they are stored as quant.sf.gz. There are 20 Gibbs inferential
replicates for each sample.
The inst/scripts/ena_downloads.R R script also shows how the column
data file coldata.csv was generated. This file contains the
phenotypic information about the 24 samples:
dir <- system.file("extdata", package="macrophage")
coldata <- read.csv(file.path(dir,"coldata.csv"))
coldata <- coldata[,c(1,2,3,5)]

The package also contains a summarized experiment object created
using the script in inst/scripts/gse_create.R. This object can be
loaded with data("gse").
Thanks to the study authors for posting their data publicly and clearly labelling their data.
