version 1.26 September 7, 2010 ------------ - Added an header-editor. - Added a file reducer/cropper. - Added the possibility to clip the signals to their pane. - Solved a bug that rendered the settingsmenu invisible on the Mac. version 1.25 August 2, 2010 ------------ - Solved a bug that caused writing invalid files and/or caused to reject opening a file because of an incompatibility while in reality the file was valid. This was caused by a localizationproblem which occured only on systems where countrysettings are used that uses a comma as a decimal separator. - Changed the name of the "Display" menu to "Timescale". - Added the entry "3 cm/sec" to the the Timescale menu. - From now on EDFbrowser will use the DPI-settings from the underlying windowmanager in order to calibrate the screen. If this doesn't work well in your situation, you can still calibrate the screen manually in the settingsmenu. - Solved a bug that caused malformed waveforms when opening large files (>4 GB) and when navigating to the end of the file. This was caused by an integer overflow. - Solved a bug in the ASCII to EDF converter (couldn't open templates). - Changed the sourcecode to improve Mac compatibility. version 1.24 June 28, 2010 ------------ - Solved a bug in the Nihon Kohden to EDF+ converter that caused a message "Can not open file *.log for reading,". version 1.23 June 23, 2010 ------------ - Changed the DFT-algorithm of the powerspectrum to an FFT-algorithm in order to avoid long computation times. - Added the possibility to adjust the blocksize for the powerspectrum (FFT). - Added an extra option to the Annotations export tool. Now you can choose to save the annotations in a comma separated textfile or in the EDFplus format. - Changed the position of the widgets in the annotation-editor window. The "Create" button will not be cut-off anymore when a monitor with a resolution of 1024 x 768 is used. - Qt has been updated to version 4.6.3 (windows version has still 4.6.2). version 1.22 june 4, 2010 ------------ - Added a docked powerspectrum which updates automatically when you navigate throug a file (PgUp,PgDn, etc,). - Added the possibility to use different backgroundcolors for different frequencyregions in the docked powerspectrum (colorbars). - Added an export function for the powerspectrum. This will export the data of the powerspectrum to a textfile. - Added a cursor to the powerspectrum. - Improved the way filters run-in. - Added an export function for annotations. This will export the annotations to a comma separated textfile. - Added a possibility to bind keys F1 ... F8 to predefined montages. This way you can quickly switch between different montages by pressing F1, F2, etc. - Removed a bug in the EDF+D to EDF+C converter that could cause a crash. - Removed a bug in the BDF+ to ASCII converter. version 1.21 may 11, 2010 ------------ - The Powerspectrum window will not block the mainwindow anymore. Now you can open multiple Powerspectrum windows (for example, to compare different blocks of data and/or different signals). - Made a printing option for the Powerspectrum. you can print the Powerspectrum to a printer, Postscript, PDF or an image by rightclicking on the curve of the Powerspectrum. - The ASCII to EDF converter now has a multiplierfactor. Cleaned up the code of the converter as well. - Fixed a bug that caused writing to a freed memory area which could cause a crash when closing the program (mainly noticeable on windows). - Fixed a memoryleak. version 1.20 may 4, 2010 ------------ - Added a power spectrum analyzer (Discrete Fourier Transform). - Removed a bug that caused wrong vertical ruler values during printing. - Removed a bug that caused a wrong screenoffset when changing the offset in the signalproperties dialog. version 1.19 april 20, 2010 ------------ - Added extra filter options: lowpass, highpass, notch, bandpass, bandstop, Butterworth, Chebyshev, Bessel, 1,2,3,...8 th order, adjustable bandpassripple or Q-factor. - Removed a bug in the BDF to EDF converter, clicking on "Select all signals" or "Deselect all signals" without a selected file, caused a crash. - Fixed a bug in the "Print to EDF" and "Print to BDF" function. Filter description in header was wrong (i.e. "LPF:" instead of "LP:"). - Fixed a bug in the Filter Dialog. When adding a new filter when signals have different samplerates, initialisation of the new filter could happen with wrong samplerate, causing a wrong frequency of the filter. - Updated Qt to version 4.6.2 version 1.18 januari 12, 2010 ------------ - added an annotation editor - solved a bug that could cause an errormessage "can not open file for reading" - solved a bug that could cause a false positive when checking the EDF-header of an EDFplus file (patientfield) version 1.17 november 4, 2009 ------------ - solved a bug in load_montage_dialog.cpp that caused a crash when loading a montage and a label was not found version 1.16 october 28, 2009 ------------ - solved a bug in the BDF+ to EDF+ converter - solved a bug in the XML parser - solved a memoryleak when using filters - solved some minor bugs - added a floating ruler - made some minor cosmetic changes - updated Qt to version 4.5.3 version 1.15 june 18, 2009 ----------- - solved a bug that could cause a crash when using crosshairs version 1.14 april 27, 2009 ----------- - solved a bug & optimized the code in the BDF to EDF converter - updated Qt to version 4.5.1 version 1.13 april 20, 2009 ----------- - added a BDF(+) to EDF(+) converter version 1.12 april 2, 2009 ----------- - bugfix release, solved a crash when removing a signal or a filter version 1.11 march 31, 2009 ----------- - added an EDF+D to EDF+C converter, it can convert discontinues files to continues files (interrupted recordings to un-interrupted recordings), can be used for BDF+D files as well - added an Emsa (*.PLG) EEG to EDF+ format converter - updated Qt to version 4.5.0 which has better GTK-style support when Gnome is used version 1.10 februari 13, 2009 ----------- - solved a bug that generated a false "read error" message when using filters at the start of the file (this bug appeared in version 1.09) version 1.09 februari 11, 2009 ----------- - solved a bug in the "Print to EDF/BDF" tools which could cause a crash - solved compilerwarnings in GCC 4.3.2 (warn_unused_result) version 1.08 december 15, 2008 ----------- - added a slider for navigating - solved a bug in the BDF+ compatibility checker - disabled the possibility to open discontinuous files (interrupted recordings) because of technical reasons version 1.07 november 5, 2008 ----------- - improved speed when a long displaytime is used - added support for the BDF+ format. Read the details here. - solved some minor bugs version 1.06 october 23, 2008 ----------- - solved a minor issue with the built-in EDF-checker - updated Qt to 4.4.3 version 1.05 september 17, 2008 ----------- - added a Finometer (Beatscope) to EDF format converter.
