API for BIOPAC file formats
Part #: ACKAPI, UPG8

BIOPAC File Format Application Programming Interface (ACKAPI) functions give software developers the ability to retrieve data from files in BIOPAC’s file format.

The API is a software library that people with programming knowledge can use to identify and parse information in BIOPAC’s ACQ binary file format. The API is a software library for programmers to use when creating applications—it is not a stand-alone data extraction program.

Curent release: ACKAPI version 3.3.1.2 — supports “typed files” and reads files created by AcqKnowledge 5.0.2 or BSL 4.4.2.

The API requires a Windows OS.

The API is the easiest way for people with programming knowledge to extract data from ACQ files for advanced analysis. Use the base functions in a variety of combinations to extract specific data from an ACQ file to use in a new application. The API allows you to:

  • Initialize an ACQ file structure
  • Close an ACQ file structure
  • Retrieve channel information
  • Retrieve samples by segment of a specified channel
  • Retrieve all the samples of a specified channel
  • Retrieve a particular sample of a specified channel
  • Retrieve samples by time slice of a specified channel
  • Retrieve Journal Text from AcqKnowledge 3.7.3 or below
  • Retrieve marker information
  • Retrieve marker text of a specified marker

Use these base functions in a variety of combinations to extract specific data from an ACQ file and then use or transform the data in other analysis programs.

ACKAPI can be used to read data from single sample rate files containing stored channels of the same length and saved with the following BIOPAC software products:

  • Windows 
    • single sample rate, non-compressed, not GLP:
      • AcqKnowledge 5.0.x, 4.1-4.4.2 and 3.7.0-3.9.1
      • Biopac Student Lab 4.0-4.2 and 3.7.0-3.7.2
  • Macintosh
    • single sample rate, non-compressed, not GLP:
      • AcqKnowledge 5.0.x or 4.1-4.4.2
      • Biopac Student Lab 4.0.0 or above
    • single sample rate, non-compressed, not GLP, saved as “Graph (Windows)”:
      • AcqKnowledge 3.7 – 3.9
      • Biopac Student Lab 3.7.1 – 3.7.2
NOTE: Access to Journal contents for files created with AcqKnowledge 4.2 and newer or Biopac Student Lab 4.0.0 and newer is NOT supported. If Journal access is required for files created with the latest BIOPAC software, use the “Windows AcqKnowledge 3.7″ export option.

The API requires a Windows OS. The implementation of these functions is compiled into a Windows 32-bit DLL called “acqfile.dll.” Although the interface is documented here in C/C++, any programming language that is able to utilize Windows 32-bit DLLs should be able to access the BIOPAC File Format API. The API was developed using Microsoft Visual Studio C/C++ and is designed to be compatible with Microsoft C++ and Microsoft Visual Basic. The API may work with other developer’s tools, but has not been tested for compatibility.

Optional Support License

The API is intended for users with some programming knowledge. Issues that the Support Department can resolve do not require and are not counted toward a license. Optional Support Licenses provide for up to 5, 10, or 20 software-related programming issues that require a programmer to resolve (SUP5, SUP10, SUP20). Contact BIOPAC to discuss license options.

ECG Electrocardiogram Amplifier for MRI

The ECG100C-MRI Electrocardiogram Amplifier records electrical activity generated by the heart and will reliably record ECG from humans, animals and isolated organ preparations. The amplifier output can be switched between normal ECG output and R-wave detection. The R-wave mode outputs a smoothed pulse with the occurrence of each R-wave. The exact timing of the R-wave […]
