Hello pyRiemann folks :)
I have been doing some work with online Riemannian Potatoes and I'm having a hard time reconciling the math and algorithms outlined in https://hal.archives-ouvertes.fr/hal…

The [docs](https://juliagaussianprocesses.github.io/KernelFunctions.jl/stable/create_kernel/#SimpleKernel-for-kernel-functions-depending-on-a-metric) recommend `SimpleKernel` for building ones own ker…

### Is there an existing issue for this?
- [X] I have searched the existing issues
### Describe your proposed enhancement in detail.
As I use these days mostly (if not only) surface analysis of fMR…

* Pseudotime for cycles doesn't make any sense, because the non-directed geodesic distances are used
* `calculate_pseudotime` shouldn't just root the trajectory as it sees fit. The rooting should…

Hi,
I have been creating a macro to analyze the intensity along regions of interest, in which I use "skeletonize" + "geodesic diameter" to select the longest path through the ROI (and then add this…

In stable version 6.4, when working in a Long-Lat LOCATION, v.distance returns geodesic distance on a sphere in meters (in the cases of point to point, a…

It could be useful to have some spherical geometry (read: geometry on the Earth surface).
In [this pull request](https://github.com/rafaqz/Rasters.jl/pull/508) I implemented a formula to calculate…

Currently we use `geopy.distance.distance` to calculate distances between gridpoints. This uses an exact algorithm, assuming an ellipsoid. For an example dataset of 25 * 53 gridpoints it takes 5min 30…

Hello,
I'm trying to use `prepareGradient` to make spatial predictions across a low-resolution raster of near-global extent.
This could be my own misunderstanding of the principles behind `prepa…

Step by Step upgrade and additions to the algorithm.
What is PCA, how does it work, when does it not give good results
Why PGA?
