Dennis thanks for replying. It has been a while sinceI revisited the forum. I come today because I am finding it difficult to get the software running. The instructions for the EDF viewer call for: 1) Make sure you have installed the prerequiste 8.5 Matlab Compile Runtime. 2) Download the compiled application from: https://github.com/nsrr/edf-viewer 3) Unzip the file and place SleepPortalViewer.exe in the desired folder.

I done the first two steps but there is SleepPortalViewer.exe file. There is a file called "SleepPortalViewerR2014bWin64.prj" And help appreciated. And what does "desired folder" mean? Is this the folder containing the EDF files (subfolders)?

Couldn't you just use any of the gazillion screen capture programs to make JPGs of each 30 second epoch of the EDF viewer and then use an open sourced converter to make the DICOM from these JPGs?

http://download.cnet.com/DICOM-Converter/3000-2129_4-75860085.html Or if it is short snippet of recording, make a screen capture video of the waveform scrolling across the screen and then make that into a DICOM file?

This FREEWARE seems interesting and DICOM capable. http://www.xnview.com/en/xnview/ Sorry, it only READS DICOM not write.

Hold on, if using Matlab, which can open EDF

and also has capability to write DICOM...

this should be no problem.

I invented, published and made open source a single EEG channel sleep/wake metric. It is called z-ratio. It has been peer reviewed and published in SLEEP, and as well the AASM has kept in the loop of possible new methods for future sleep/wake automation. IT DOES NOT STAGE SLEEP, it provides a METRIC to gauge the relative contribution of slow to fast EEG within a single channel of EEG initially in 2 seond epochs, now down to 1 second epochs. First published in 1990.

The bibliography compilation of publications can be found here: www.z-eeg.com

The foundational basis was also recently corroborated by a study out of Boston's Mass General: http://journals.plos.org/ploscompbiol/article/asset?id=10.1371/journal.pcbi.1003866.PDF

Feel free to let me know how I can help. Claude

ADMINS: I have applied for download rights, but have not heard back. What else do I need to do to be able to download the EDFs and start using them to investigate z-ratio on this open source of cases?

By the way, Teuniz has included z-ratio in his Open Sourced EDF browser http://www.teuniz.net/edfbrowser/

I would like to venture into Matlab to bring my invention for EEG sleep/wake analysis outside of the sleep vendor systems that I have been using up to now. REMbrandt, Compumedics. A colleague has written a z-ratio component for me in his EDF Browser http://www.teuniz.net/edfbrowser/. I wish to show how z-ratio is impervious to differing power analysis routines. So I would like to perform different power analysis (FFT, Wavelet, etc) on the same EDF fle under Matlab and then perform z-ratio independently on the resulting power analyses output. www.sleep-wake.com/z-ratio_presentation.pps www.sleep-wake.com/zomnography.swf www.somnonaut.com

Any help appreciated.
