The goal of vetperf is to provide functions for extracting perfusion parameters from measurements obtained from veterinary MRI images.
You can install the released version of vetperf from CRAN with:
install.packages("vetperf")Load your data from csv (check out the great data.table package!) and run vetperf.data on your data. You will get a table holding the perfusion parameters.
library(data.table)
library(vetperf)
animals <- fread('path/to/your/data.csv', stringsAsFactors = TRUE)
perfdata = vetperf.data(animals, arrival_frame = 9, delta_t = 1.6, echo_time = 0.03, baseroi = "cs")Can be found in the package vignette. For an explanation on the format of the data frame, take a look at the examples or at the code documentation.
