Thanks, was thinking the same thing but wasn't able to figure out how to export a modified file as new.
Is anyone having issues with the 'Save As' function in EDFBrowser? Love the versatility of this program, but after inverting an upside down ECG waveform using the 'Organize' function, I'm not able to save the modified file. The 'Save As' button is now always greyed out.
I'm sure I used to be able to do this save a modified EDF file. I'm running version 1.62.
