Features:

  • supported fileformats: EDF, EDF+, BDF, Nihon Kohden*
  • supports montages
  • annotations
  • precise measurements by using crosshairs
  • zoomfunction by drawing a rectangle with the mouse
  • shows signals from different files at the same time
  • built in ASCII to EDF converter
  • built in EDF/EDF+/BDF to ASCII converter
  • built in Nihon Kohden to EDF+ converter (including annotations)
  • built in EDF/EDF+/BDF compatibility checker
  • available for Linux and Windows

What is new in this release:

  • The activity of the floating ruler will now be stored in the montages as well.
  • Added a filter to the annotationslist.
  • Modified the BI9800 to EDF converter to make it work with 48-hour recordings.
  • Made the viewtime (fileposition) indicator configurable. Added the date to the viewtime indicator in the left down corner of the screen. This can be configured in the settings menu.
  • Made the window title bar configurable. This can be configured in the settings menu.
  • Fixed a bug in the EDF+D to EDF+C converter.
  • Added the possibility to save and load different color schemas.
  • Added support for the Unisens fileformat. You will find the converter in the Tools menu.
  • Added the possibility to save and load colorschemas.

What is new in version 1.52:

  • Added an SCP-ECG file to EDF+ converter. Bimodal compression or customized Hufmanntables are not supported. Lossless compression using default Hufmanntable and/or 1th/2th differences is supported. Character-encoding other than ASCII/Latin-1 is not supported.
  • Added two shortcuts (Plus and Minus keys) to increase or decrease the amplitude of the signals (sensitivity).
  • Added the possibility to choose between little endian or big endian encoding in the binary/raw to EDF converter tool.
  • Increased the number of pre-defined montage shortcuts from 8 to 12 (keys F1 to F12).
  • Added the possibility to use aliases for the signallabels on the screen.
  • Qt has been updated to 4.8.5.

What is new in version 1.51:

  • Added a Manscan MICROAMPS binary file to EDF+ converter.
  • Solved another bug in the sorting algorithm used for the annotationlist.

What is new in version 1.50:

  • Fixed a bug in the ECG heartrate detection algorithm when a high samplerate was used.
  • Improved the sorting algorithm used for the annotationlist, it was very slow when the annotationlist contains more than 10000 annotations.
  • Added the possibility to adjust the samplerate divider for all signals at once in the reducer/decimator tool.
  • EDFbrowser now checks online for a newer version during startup. This can be switched off in the settings menu.

What is new in version 1.49:

  • Added a binary/raw to EDF converter tool.
  • Solved a bug in the "Import annotations" tool.
  • When importing from ascii, wrong onset-times were created
  • when there were more than 7 digits after the decimal point.
  • Added a scrollbar to the options- / settingsdialog in order to make it fit
  • on screens with low vertical height (modern laptops with 16:9 screen).
  • Removed GTK-style support because it's broken.
  • Updated Qt to 4.8.4

What is new in version 1.48:

  • Added sub-second precision for annotations when using the Nihon Kohden converter. (Before, the onsettimes of the annotations were rounded to seconds.)
  • Added Z-EEG measurement.
  • Improved the header editor/fixer. Now it accepts files with a maximum of 2048 signals. (Before it was limited to files with a maximum of 256 signals.)
  • Now, it can also fix the digital minimum/maximum fields in the header (e.g. when a broken number was written instead of an integer number).
  • Updated Qt to 4.8.2

What is new in version 1.47:

  • Solved a bug that caused a crash when saving an EDF- or BDF-file after importing annotations.
  • Changed the "Export ECG RR-interval" tool in such a way that you can easily export the whole recording. Also, now it's possible to import them as annotations directly.
  • The tool "Import annotations/events" can now also import the duration of an annotation/event (from ASCII- or XML-files).
  • Added the possibility to hide or unhide annotations from the screen. (Right-click on an annotation in the annotationswindow.)

What is new in version 1.46:

  • Solved a bug that caused a crash when the "Abort" button was clicked when opening a BDF-file.
  • Solved some small bugs and made some enhancements.
  • Updated Qt to 4.8.1.

What is new in version 1.45:

  • Added the possibility to disable scanning for annotations or triggers
  • when opening a file, depending of the filesize.
  • This can be usefull when working with big files that take
  • a lot of time to read-in annotations, events or triggers.
  • (Due to the nature of the EDF-format, the annotations-channel(s)
  • needs to be read from the beginning till the end of the file.)
  • In the "Settings -> other" dialog you can adjust the filesize
  • which above EDFbrowser will not scan the file for annotations.
  • (between 100 MB and 10 GB)
  • Extended the capabilities of the header-editor. Now it can also fix
  • files that have a wrong number of datarecords written in the header
  • or when the file does not end at the boundary of a datarecord.
  • See the manual for the details.
  • Improved the ECG heartrate detection algorithm.
  • Fixed some bugs related to signals with inversed polarity
  • (i.e. when physical maximum is lower than physical minimum).

Requirements:

  • Qt
  • GCC
