Add a hotkey help dialog with lists of hotkeys

1

@cbrnr Currently there is no way for users to know some hidden hotkeys, such as Ctrl + mouse wheel etc. I am thinking to add a dialog with all the...

I compared some files in SigViewer and in Matlab, and see the signals and events in SigViewer are sometimes not exactly accurate. Using effective sample rate to display events is...

One of our collaborator got seriously confused, saying he never saw the stream he expected... turned out that stream is a text event stream and he was looking for it...

The order of the streams in XDF file seems to be random

I know this is not a SigViewer problem but I thought it's easier to discuss it here. Also currently the way libxdf loads the streams don't follow the exact stream...

A loophole

11

@cbrnr Just noticed a loophole when debugging Stefan's file: Before I thought string streams are always irregular streams, but turns out Stefan's file has a stream that is 5000Hz but...

Favor effective rate over nominal rate, because the latter could be inaccurate

Resampling XDF with multiple streams @ variable sampling rates

5

SigViewer requires resampling when opening an `.xdf` file with multiple streams @ variable sampling rates-- unfortunately resampling is causing SigViewer to crash. Resampling rates tested: `500, 100, 1 Hz`

Some biosignals require filtering before they can be visualized, e.g. EEG recorded without any HP filter typically has huge drifts. The auto-centering function, which centers each channel around its mean,...
