Spiked qPCR primary analysis Spiked qPCR primary analysis
This script is for analyzing raw eDNA qPCR data. It is designed to efficiently concatenate qPCR data from multiple plates exported as *.csv files. It will assist with completing several QA/QC checks and output documentation of these checks as well as helpful files for further review.
Operational Aftershock Forecasting Operational Aftershock Forecasting
The Operational Aftershock Forecasting server runs continuously in the cloud, monitoring the USGS ComCat earthquake catalog. It automatically generates aftershock forecasts and publishes them on the earthquake event pages. The analyst utilities are GUI programs that are used by analysts to evaluate the operation of the OAF servers, and make adjustments to the statistical model used by...
pymaxspots: Computing and connecting horizontal gradient maxima in potential-field geophysics pymaxspots: Computing and connecting horizontal gradient maxima in potential-field geophysics
"Max spots" or "maxspots" refers to the locations of the local maxima of the horizontal gradient of potential fields such as gravity or magnetic anomalies. Because maxspots mark locations of abrupt change in the anomalies, they can be used to identify the edges of subsurface features with significant contrasts in density and/or magnetization, such as faults, intrusions, or lithologic...
Freshwater fish biodiversity and distribution in the Northeastern United States Freshwater fish biodiversity and distribution in the Northeastern United States
This software contains 3 separate R Markdown files and 1 R script file that comprise an analysis to 1. collate freshwater fish survey data from within the northeastern United States, 2. develop separate models to predict the probability of occurrence and the proportional abundance of 53 freshwater fish species, and 3. combine model results by fish species traits and habitat...
R workflow for quantifying inter-population and inter-individual variation in heat stress response mRNA expression profiles in wild brook trout (Salvelinus fontinalis) populations R workflow for quantifying inter-population and inter-individual variation in heat stress response mRNA expression profiles in wild brook trout (Salvelinus fontinalis) populations
Brook trout are a recreationally important fish species that need cold water for survival. The objective of this study was to quantify within- and among-population variability in HSP47 and CIRBP expression in four wild populations of brook trout (Salvelinus fontinalis) to quantify seasonal changes in gene expression. The code release contains a R script for the analysis of brook trout...
