EDFbrowser working with discontinuous EDF+ file

by Forrest Sheng Bao http://fsbao.net

EDFbrowser is an open source EDF Browser. EDF/EDF+ is an open file format for biomedical time series, especially EEG and ECG/EKG signal.

But, the pain is, new (version 1.08 or later) EDFbrowswer "disabled the possibility to open discontinuous files."

I consulted the author, Teunis van Beelen, and got a solution from him.
  1. Open the file mainwindow.cpp in a texteditor.
  2. Comment the lines 1293 to 1310. Put /* and */ at the beginning and end of following code
    if(edfhdr->discontinuous)
    {
    if(edfhdr->edf)
    {
    UI_Messagewindow popuperror("Error", "EDFbrowser can not show EDF+D (discontinuous) files.\n"
    "Convert this file to EDF+C first. You can find this converter\n"
    "in the Tools menu (EDF+D to EDF+C converter).");
    }

    if(edfhdr->bdf)
    {
    UI_Messagewindow popuperror("Error", "EDFbrowser can not show BDF+D (discontinuous) files.\n"
    "Convert this file to BDF+C first. You can find this converter\n"
    "in the Tools menu (EDF+D to EDF+C converter).");
    }

    free(edfhdr->edfparam);
    free(edfhdr);
    fclose(newfile);

    return;
    }
    Now compile the source code by executing qmake && make and you are done.
