Data from: Exploring the impact of read clustering thresholds on RADseq-based systematics: an empirical example from European amphibians.

This repository contains genetic sequences obtained from Hybrid-Enrichment and RAD sequencing protocols of the amphibian genera Discoglossus, Lissotriton, Rana and Triturus, as well as phylogenetic trees inferred from the RADseq data. This data was generated for the manuscript "Exploring the impact of read clustering thresholds on RADseq-based systematics: an empirical example from European amphibians.", in which we tested the influence of the clustering threshold used to assemble RADseq data on downstream phylogenetic inferences. Details on the data generation and analyses can be found in the manuscript and related supplementary materials.

The repository is organised as follow:

-> Hybrid-Enrichment: alignments of the Hybrid-Enrichment markers in phylip/fasta format (with one subdirectory for each of the four datasets assembled: Discoglossus, Lissotriton, Rana, Triturus)

--> RADseq: Assemblies and phylogenetic trees obtained from a RADseq protocol

    --> Assemblies: RADseq assemblies (complete loci sequences and SNP matrices, spreadsheets with assembly metrics). Divided into "iCT" (assemblies produced with 23 different intra-sample Clustering Threshold [iCT] and a fixed between-samples Clustering Threshold [bCT]) and "bCT" (assemblies produced with a fixed iCT and 23 different bCT). Both iCT and bCT are further divided in four sub-directories corresponding to the four datasets: Discoglossus, Lissotriton, Rana, Triturus)

    --> Trees: Phylogenetic trees inferred from the aforementionned assemblies. Divided into "iCT" (RAxML concatenation trees inferred from the assemblies with different iCTs) and "bCT" (RAxML concatenation trees and Tetrad species trees inferred from the assemblies with different bCTs).
