Import raw .abf files as a dataframe

import_ABF_file() is a wrapper around abftools::abf2_load() and abftools::MeltAbf(). It converts the array from abf2_load() into a dataframe, and it also converts time to minutes.

Usage

import_ABF_file(file_name)

Arguments

file_name

Filepath to an .abf file (e.g. "Data/23711004.abf")

Value

A dataframe with 5 columns:

• time Time value from Clampfit which is in milliseconds x 10. For example, 5 seconds = 50000 in this column.

• episode Character value (e.g. "epi1", "epi2") which corresponds directly to "sweep" in Clampfit.

• current Current in pA.

• voltage Voltage in mV.

• time_sec Time in seconds.

Details

The file progresses from .abf to an array and then to a dataframe that can be easily manipulated in R.

Examples

import_ABF_file(import_ext_data("sample_abf.abf"))
