Note

NeuroExplorer tries to identify the data file type from the file extension.

Some file extensions are used by several file formats and NeuroExplorer may be unable to identify what is the file format of the file that is being loaded.

For example, a .nev file can be either a Neuralynx data file or Ripple Neuro data file.

You can specify what file format corresponds to a specific file extension. See Dealing with Unknown File Format Error.
