Tutorial & data examples for users

[tmedani]

Hi Sampsa,

I'd like to try your toolbox, do you have any tutorials or any examples guidances for first steps & examples data.

Thanks Bests regards

Hi Takfarinas,

Thanks, you are very welcome to try the toolbox and to participate in the development. Indeed, more tutorials will be needed, I will add some more materials asap. The easiest start is probably the import ASCII option and the ASCII import folder in the data folder. By following the instructions in the import file (.ZEF) in the folder, one can quickly obtain a multilayer segmentation to be examined. I will also try to provide a complete tutorial project with a 3D mesh through an open data link in the future. Currently, the spherical example in the data folder has a low-res 3D mesh with a reconstruction in it for a demonstration. The basic instructions in the wiki will give guidance for creating a volumetric model. I am working on to provide test data. To begin with, the easiest option is to place synthetic sources in the brain. This can be done with the find synthetic source function (multiple sources can be obtained by inserting the coordinates and magnitues as arrays [x_1 x_2 x_3] etc.). The resulting synthetic data can then be inverted using the inverse functions. Based on our experience the reconstruction quality obtained with the synthetic sources corresponds to that of clinical data, if the sources in the latter case are focal enough.

Hopefully you can successfully create a system. I am interested to hear how it goes and of your experience.

With kind regards,

Sampsa

We will prepare script examples in scripts folder for demonstrating the usage.
