snapcount: R/Bioconductor Package for interfacing with Snaptron for rapid querying of expression counts

snapcount is a client interface to the Snaptron webservices which support querying by gene name or genomic region. Results include raw expression counts derived from alignment of RNA-seq samples and/or various summarized measures of expression across one or more regions/genes per-sample (e.g. percent spliced in).

Shared Sample Count (SSC): counts total number of samples in which 2 different junctions both occur in.shared_sample_counts
Tissue Specificity (TS): produces a list of samples with their tissues marked which either contain queried junctions (1) or not (0); can be used as input to significance testing methods such as Kruskal-Wallis to look for tissue enrichment (currently only works for the GTEx compilation).tissue_specificity
