MNE-Python RawBrowser

[Martin Schulz]

Dear pyqtgraph-community,

my name is Martin Schulz and I am currently participating in the Google Summer of Code for MNE-Python. My project is the reimplementation of the RawBrowser which is displaying the channels from EEG/MEG-data over time. Thanks to your modular and well documented package I could quickly start with a pyqtgraph-prototype and I am currently trying to implement all the features we need. To display the usually large datasets, I only show the time&channels of the current viewRange as in your hdf5-example. I extended it to dynamically load PlotCurveItems for channels if the yRange changes instead of having them all in the scene. PlotCurveItems seem to provide a better performance on initialization than PlotDataItems. In the adjacent schematic I have outlined the structure of my current prototype.

What do you think about this? I would be happy about comments or maybe hints if I used something not the way it is supposed to be used or it could be used better.

Thank you very much for your work, I am more and more seeing how many problems you solved in advance. It is a lot of fun to use pyqtgraph and it facilitates advancing with my project a lot.

Best wishes

Martin

Hi Martin,

This sounds like a great project. Our group has a lot of overlap with some of things we are working on. 

Are you blogging about it somewhere. We might be able to share some results.

Dear Christopher,

thanks a lot for your reply. Yes, I am blogging weekly here.

Are you working on a pyqtgraph-data-browser too?

Thank you very much for the offer, it would aid me a lot to see how others tackled the (performance)-problems of visualizing large datasets.

I saw that you are invested in neuroscience and medecine too being a MD/PhD (I am a 5th year medical student working on my doctoral thesis about MEG/EEG pain-neurophysiology).

Are you able to use Open-Source-Software as the plots from MNE-Python in clinical settings e.g. for diagnostics too?

Best wishes

Martin

Hi Martin

i will check out your blog. We are using pyside2 and pyqtgraph with our own libraries and MNE

given that it is a foundational library for eeg in python we plan to support it more in our eeg reader/an orator.

We currently support EEG and our own hdf5 based format.

We are doing research but are more focused on clinical EEGs that most in the mne community
