IVSummary: Report I-V relationship of a list of abf objects.

In Crystal-YWu/abftools: ABF Tools: Toolbox for Visualising and Analysing Electrophysiology ABF2 Data

Description

Report I-V relationship of a list of abf objects.

Usage

IVSummary(abf, intv = NULL, conductance = FALSE,
  current_channel = GetFirstCurrentChan(abf),
  voltage_channel = GetFirstVoltageChan(abf), group = NA,
  unit = FALSE)

IGVSummary(abf, intv = NULL,
  current_channel = GetFirstCurrentChan(abf),
  voltage_channel = GetFirstVoltageChan(abf), group = NA,
  unit = FALSE, raw = FALSE)

Arguments

abf	a list of abf objects.
intv	OPTIONAL, a list of intervals.
conductance	Only used in IVSummary(), if TRUE, same as calling IGVSummary()
current_channel	current channel id, 1-based.
voltage_channel	voltage channel id, 1-based.
group	OPTIONAL, add a "Group" column to the returned data.frame.
unit	whether to add unit columns to the returned data.frame.
raw	whether to return raw wide format.

Details

This function calculates episodic mean values of current and voltage channels and thier corresponding SEMs given a list of abf objects. IGVSummary() also calulates conductance. However, while averaging conductances gives correct results, SEM of conducetance may not properly represent the actual errors. Though also reported in the returned data.frame, it is not suggested to plot SEM Conductance since it can be mis-interpreted in some cases.

Value

a data.frame
