  Supported Formats

*Persyst has created built-in data readers for most supported formats so you can open nearly any EEG record in Persyst, regardless of the file format or the system it was recorded on. For a small number of some formats, the data reader is supplied by the OEM software vendor and installed with Persyst for a seamless experience.  This means that to read these file formats in Persyst, either the original EEG software must also be installed with Persyst, or an additional data reader from the OEM vendor must be installed on the computer instead, otherwise there will be an error that the file cannot be read. Therefore, if you have data files of the following formats and do not also have the OEM software installed with Persyst, and/or are experiencing an error, please contact Persyst Support for help in working towards a seamless experience in Persyst.
