I have been tearing apart designs and snippets trying to get the combination of buttons and drop down menus on runtime 1. So far I seem to be doing alright, However I looked at a snippet that used a sourceselector And found no mention of it in my manual.

I will be recording and playing back 4 to 8 channels of data from my qds amp. I think I have it hooked up to the edf file recorder just fine. What I need to know then is how to get all 4-8 channels out through the reader and into a polygraph and other elements.

I was wondering if there is a way to do this by setting properties in the device set. I hope this is modestly clear it is friday pm and I'm a bit out of energy

Thanks

George,

I updated manual, it has now the SourceSelector section.

The most common and easiest way to read multichannel EDF data is to use the EDFFileReader and connect it directly to Polygraph and other elements just the same way as QDS element.

It is also possible to use DeviceSet (select "EDF file" in drop down list and choose the file). It makes sense if you wish to make the selection of the file as a global setting (set immediately in all other designs which use DeviceSet), or to switch between QSD and EDF file dynamically (that way the SourceSelector is not necessary, but you still need to reinit design after each such change - see description in SourceSelector).

Thanks as always for the quick response.

I will read this over and see what I can do
