Week 12: Blog Post (#6)

Last week, I worked on several steps to finalize my project.
Some work was put into correcting and improving my pull requests, so they can be merged soon. I created an example file to demonstrate the useability of this project, and opened up a new pull request for it (next to another PR, that introduces the plotting support I implemented the previous week).
As mentioned in my last blog post, I also thought about an alternative solution, i.e. to create a genuine plotting function for SourceTFR. But as I already suspected, this will not work without a lot of additional work. I originally intended to introduce a new type of plot derived from MNE's "TimeViewer", where you can not only skim along the time axis through the plotting GUI, but also along the frequency (and maybe the epochs) axis. After trying out some stuff, my best intuition to reaching this goal would be to simplify the "TimeViewer" class, and make it some kind of a "AxisViewer" class. This class would allow a developer to decide which axis (or even multiple axes) should be manipulable through the GUI. Yet, this would be only a part of the work, as this does not include the actual plotting function used by SourceTFR, and also would only work for the plots made on surface type source level data (since volume type source level data employs an entirely different plotting GUI). In my opinion, this functionality should rather be added later, so I can now concentrate on the finishing touches of the rest of the project.
One such finishing touch is for example time and memory saving computation of tfr_stockwell, which is for now only available for tfr_morlet and tfr_multitaper. I already made attempts to tackle this problem, and currently try to make it pass the equivalence tests. But this will definitely be one of the things to do this week, as it will have big implications on the practical useability of the function.

Another thing I worked on last week (and will continue to work on this week) was the project page where I'll upload my final results next week. I decided to create a GitHub gist for this purpose, since it is simple and good looking at the same time. Most of the gist is already finished, only the links to the PRs and some direct examples will need to be added there. So I hope, everything will work out this week, and I'll be able to show you a nice conclusion on my Google Summer of Code project until next week.

So, for the last time (this summer?!): Stay tuned!
