Overview of all example Matlab scripts

Here you can find some example Matlab functions and scripts that show specific analyses done in Fieldtrip or that can be used in conjunction with Fieldtrip.

We invite you to add your own example scripts or frequently asked questions to the wiki. Also tutorials can be added. Every time you explain somebody something about Fieldtrip, please consider whether you could use the wiki for this so others can learn from it as well. If you want to contribute one of your scripts, please add it directly to the wiki or contact us.
