Information About the File Formats
.TXT & .TXT (RAW)
Text files are the standard format to store OpenSignals data. By default, the data is stored in a .TXT file containing the raw, digital sensor data with values ranging between 0 and (2n-1), with n being the signal resolution set for the acquisition (8-bit or 16-bit). These files are listed above as .TXT (Raw).
The converted sensor data – the data in each sensor’s correct physical units – is stored in an additional .TXT-file with an “_converted” appendix to its name. These files are listed above as .TXT only.
Find out more about the .TXT file content and structure and its .CSV compatibilities in the following article:
[Support Article] OpenSignals Sensor File Specifications (.TXT Format)
.H5/.HDF5 – Hirarchical Data Format
The .H5/.HDF5 file format is a data format developed by the The HDF Group and is a data format designed to store large amounts of n-dimensional datasets and all relevant metadata in a single file. This is the primary format used by OpenSignals to read and store raw and processed sensor data.
.EDF – European Data Format
The European Data Format (EDF) is a simple and flexible format for exchange and storage of multichannel biological and physical signals. This format a commonly supported data format in a variety of biosignal processing software solutions and can be used to facilate the export of OpenSignals data with third-party solutions.
