Data and scripts from: Balanced polymorphism fuels rapid selection in an invasive crab despite high gene flow and low genetic diversity

Carcinus maenas is a globally invasive species which spreads and thrives
across a range of temperate environments. In the northwestern Pacific, the
species has spread across >12 degrees of latitude in 10 years from
a single source, following its introduction <35 years ago. Using
six locations spanning >1,500 km, we examined genetic structure and
selection to temperature using 9,376 Single Nucleotide Polymorphisms
(SNPs) derived from cardiac transcriptome sequencing. Data in this
repository includes information on sequenced samples (*.csv, *.txt), a
cleaned transcriptome assembly after expression filtering (*.fasta),
transcriptome annotation from EnTAP (*.tsv), list of transcripts removed
from analysis after mapping (*.txt), high-quality SNPs identified from the
transcriptome sequencing with GATK (seven files representing different SNP
sets used in the analysis; *.vcf), and four custom scripts used in
processing SNP data (*.py and *.R). Raw sequence data is archived in
GenBank's SRA. 2015-2016 samples: BioProject ID PRJNA690934 and
BioSample IDs SAMN17267686–SAMN17267781. 2011 samples: BioProject ID
PRJNA283611 and BioSample IDs SAMN03653390–SAMN03653413.
