Currently, Athena is able to manage the following file formats which can be processed as time series:

  • EDF (European Data Format) files, a standard file format designed for exchange and storage of medical time series, read through the Brett Shoelson's function
  • mat files, which can be matrixes (in this case, the locations' file will be required during the temporal and spatial average step) or structures which can be contain a data matrix, the sampling frequency and the locations' list
  • txt files, which are text files in which the values of the signals are separated by a space, and in each row can be represented all the samples of a single location or the sample of all locations at a given instant
  • csv (comma-separated values) files, in which the values are separated by a comma, and can be disposed in the same way as the txt files
  • xls and xlsx files, in which the data is in Microsoft Excel's spreadsheets
  • eeg, BrainAmp/BrainVision files (related vhdr files are needed to be in the same folder)

The data files can be inside a single directory or each inside a its directory, but in this case it is necessary to use the path of the directory which contains all these directories as directory path in the various steps.



The subjects' file and the locations' file are currently usable as mat files which can be numeric matrixes, string matrixes or cell matrixes.
