inspect_binFile_brand: Identify the Device Brand from a Binary File

In GGIR: Raw Accelerometer Data Analysis

Identify the Device Brand from a Binary File

Description

This function identifies the brand of a device (e.g., GENEActiv or MATRIX) based on the contents of a binary file. If the file is unrecognized, it returns a default value indicating the device is not recognized.

Usage

inspect_binFile_brand(filename)

Arguments

filename

The path to the binary file to be inspected.

Details

The function performs the following steps:

1. Reads the file header to check for the presence of a "Device Type" field.

2. If the device type contains the string "GENEActiv", the device is identified as a GENEActiv device.

3. If the "Device Type" field is not found, it checks for a MATRIX device by validating a specific header value ("MDTC").

4. If neither device type is detected, the function returns "not_recognised".

Value

A character string representing the detected device brand:

• 2: Indicates the device is a GENEActiv device.

• 7: Indicates the device is a MATRIX device.

• "not_recognised": Indicates the file's brand is not recognized.
