Thank you very much for your valuable feedback on the EDF Editor.
We have removed that false positive warning and include this in our new release for the tool EDF-Editor/Translator.
Here is the link to the new release is: https://github.com/nsrr/edf-editor-translator/releases/tag/2.1.0 .
Thank you for helping improve the quality of our tools and don't hesitate to let us know of anything else you may run into.
It's great to hear from you and we are happy to help.
For your first question, it seems you tried to load your own XML annotation, but EDF Viewer is created to work with NSRR provided annotation files.
Secondly, EDF Viewer does visualize signals with actual physiological units. For example, we show pulse with unit BPM and SpO2 with % (see images below).
Responding to your last question, the loading of EDF and annotations takes a couple of minutes and it may take longer depending on the size of files.
Our EDF Viewer requires MATLAB Compiler Runtime version 8.5 (MATLAB R2015a) to run, which needs operating system version to be >= Windows XP or >= Mavericks if you are a MAC user. We also recommend at least 2GB ram to ensure the application runs properly.
We can better help with your problems if you can provide more information about what EDF and annotation you tried to load and what operating system you were working on.
