ABF_plotter.R

This simple script allows plotting data from ABF files using ggplot.

Required packages

• ggplot2
• readABF

(install with install.packages(c("ggplot2", "readABF")))

Usage

1. Download the ABF_plotter.R script from this repository.
2. Create a new R script in the same directory as the ABF_plotter.R script.
3. Load the ABF_plotter.R script in your R script using the source() function and read the ABF file using the readABF() function from the readABF package.

library(readABF)
source("ABF_plotter.R")

recording <- readABF("recording.abf")

4. You can now plot the data using the plotABF() function.

# Plot data from 500 to 510 seconds
plot_ABF_data(recording, sweep=1, channel=1, time_from=500, time_to=510)

# As above, but highlight the x range from 501 to 503 seconds
plot_ABF_data(recording, sweep=1, channel=1, time_from=500, time_to=510, highlight_x_range = c(501, 503))

# Change the highlight color to red, plot time 200-400s but start the x axis from 0
plot_ABF_data(recording, sweep=1, channel=1, time_from=200, time_to=400, reset_time = TRUE,
    highlight_y_range = c(-60, -40), highlight_color = "red")

5. You can also print information about the recording using the print_ABF_file_info() function.

print_ABF_file_info(recording)
