Using the power of the BIOPAC scripting language

1. Automate artifact removal2. Identify outliers for manual inspection3. Batch process

Additional analysis techniques

AGENDA



1. Binned analysis2. Area under the curve

Questions and answers

• AcqKnowledge: used by thousands of labs around the worldand has been cited in thousands of peer reviewed publications.

• AcqKnowledge: an interactive, intuitive program that lets youinstantly view, measure, transform, replay and analyze data.

• AcqKnowledge: Perform complex data acquisition, stimulation,



• AcqKnowledge: Perform complex data acquisition, stimulation,triggering and analyses using simple pull-down menus anddialogs—no need to learn a programming language or newprotocol.

• AcqKnowledge: included with each BIOPAC MP150, MP36R, andB-Alert system, and can also be purchased separately

Resampling and artifact removal:

1. Resample and duplicate the EDA data

2. Median smoothing and low-pass filter

3. Obtain an artifact detection waveform

How to get great EDA Data



4. Identify artifacts above a certain threshold

5. Review and fix large artifacts manually via Connect Endpoints if necessary

How to automate using scripts

Resample script

Process script

Place the scripts in the menu




BBS reference and free sample scripts

Ability to modify existing analysis routines

Batch processing simple example:

Open and resample all files in a folder, save each under a new name

Some further possibilities for automation:

1. Automatically identify the EDA channel in each file2. Customize the EDA analysis parameters




2. Customize the EDA analysis parameters3. Perform the actual analysis via a script4. Analyze EDA and other physiological signals at the same time, for all participants

EVEN SIMPLE SCRIPTS SAVE A LOT OF TIME
