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.
