Generic qPCR Limit of Detection (LOD) / Limit of Quantification (LOQ) calculator

This script is designed to analyze qPCR data for many replicates of known concentration DNA standards and determine the limit of detection (LoD) and limit of quantification (LoQ) for use in environmental DNA applications. It is written in the hopes that users with even limited knowledge of R will be able to successfully use the code to analyze their own data in the same way as other eDNA researchers to get similar results and automatically generate plots to visualize the data. The code has 5 lines for user input and requires a few simple restrictions on the input data, but after that the user should be able to run the code without any further coding or interventions. No R programming ability is required to run this...

Code to analyze multi-lab LOD / LOQ study data

This code supports the manuscript "Reporting the limits of detection (LOD) and quantification (LOQ) for environmental DNA assays". The code analyzes outputs generated by another more generic code to analyze raw qPCR data for LOD and LOQ. This code requires the generic LOD / LOQ calculator script to read in and prepare the data, with additional script runs as described in comments within this code. We wrote this code to specifically analyze our data and generate the figures for the above-mentioned manuscript, however it could be adaptped by a savvy programmer to run similar analyses.
