ABF Import Dialog

This page describes the contents of the Axon Instruments ABF data import dialog.

Parameters

File parameters. Only parameters that apply to the current file are displayed. The parameters are:

Comment
A comment supplied by the user
Created
The file creation date and time
Creator
The program that created the file
Mode
The data acquisition mode. The mode is one of:
Mode
Clampex
Gap-free
Fixed-length events
Variable-length events
High-speed oscilloscope
Sampling interval
The interval between frames in the file
Second interval
The second interval between frames in the file. ABF files recorded in Clampex mode may use an initial sampling interval for the first part of each episode and a second sampling interval for the second part. If the file is recorded with two sampling intervals, this entry is the second sampling interval.
Second start
If two sampling intervals are used, the sample number from which data points are sampled at the second sampling interval.
Runs
The number of runs averaged for each recorded episode
Stimulus
ABF files recorded in Clampex mode may contain a stimulus. If a stimulus was used during recording, the source of the stimulus waveform. Possible stimulus sources are:
NameSource
EpochsThe stimulus template is stored as a sequence as epochs
DAC FileThe stimulus source is a sequence of data values

Episodes

A list of the episodes in the file. For each episode the following information is displayed:

Index
A sequential index for the series within the file
Time
The starting time of the episode within the file
Frames
The number of frames acquired within the episode, that is, the number of data values recorded for each channel.

To specify that data from a given episode be imported, select that episode in the list. Any combination of episodes can be selected.

Channels

A list of the acquired data channels recorded in the file. You can select an arbitrary collection of channels. For each channel the following information is displayed:

Index
A sequential index for the channel within the file
Label
A text label for the channel, provided by the user during recording.
Units
The units of the channel data, provided by the user during recording.

To specify that data from a given channel be imported, select that channel in the list. Any combination of channels can be selected.

Tags

A list of the tags recorded in the file. For each tag the following information is displayed:

Index
A sequential index for the tag within the file
Time
The time of the tag within the file
Type
The tag type. The type is one of:
Type
Time
Comment
External
Voice
Comment
The comment associated with a comment tag

Data

A graph of the currently selected data.

Vertical lines delimit the data that will be imported. You can move the lines by dragging them with the mouse.

Include

Data
If this box is checked, the selected data is imported.
Stimulus1
If this box is checked, the first stimulus waveform corresponding to the selected data is imported. This box is disabled if the first stimulus was not used.
Stimulus2
If this box is checked, the second stimulus waveform corresponding to the selected data is imported. This box is disabled if the second stimulus was not used.
Tags
If this box is checked, the tag times and comments are imported. These will follow the waveform columns.
Time
If this box is checked, the first (leftmost) column of imported data contains time values relative to the beginning of the episode.

Buttons

Import
Import the selected data into the analysis program.
Section
Displays the ABF section dialog.
Cancel
Cancel the import and close the dialog.
