| This tutorial uses Sabine Meunier's somatotopy experiment, called ''TutorialCTF ''in your Brainstorm database. | The main window includes a graphical batching interface that directly benefits from the database explorer: files are organized as a tree of subjects and conditions, and simple drag-and-drop operations readily select files for subsequent batch processing. Most of the Brainstorm features are (or will be) available through this interface, including pre-processing of the recordings, averaging, time-frequency decompositions, and computing statistics. A full analysis pipeline can be created in a few minutes, saved in the user’s preferences and reloaded in one click, executed directly or exported as a Matlab script. |

| The ''Processes ''tab in Brainstorm window is a very generic tool that can be used to apply a function or extract data from any set of data files (recordings or sources). Its main applications are: pre-processing, averaging, and data extraction. <<TableOfContents(2)>> == Files to process == First, you have to select the files you want to process. You can drad'n'drop any node that contains recordings or sources from the database explorer to the ''Processes ''list. * Click on sources file: Subject01 / !StimRightThumb / ERP / MN:MEG(Kernel). Drag'n'drop it to the empty list in ''Processes ''list. * Click on condition: Subject01 / !StimLeftThumb. Add it to the list. * Click alternatively on the ''Sources'' and ''Recordings'' buttons in the ''Processes'' tab. This indicates if you are going to process sources or recordings files. Observe that the number of files (the numbers indicated in brackets) changes according to the modality selected.<<BR>><<BR>> {{attachment:panelProcesses.gif}} * Note that you can put almost anything in this list: recordings, sources, conditions, subjects, even the whole procotol. It will take recursively all the recordings or sources files that are contained in each node. == Process selection == * Select ''Sources''. Click on ''Run''. This big window appears:<<BR>><<BR>> {{attachment:panelStatRun.gif}} == Next == This is the end of the first tutorial, based on CTF MEG recordings. Other important notions are going to be introduced in a tutorial based on EEG data : clusters of electrodes, and statistical analysis. But please go again through all the importation / anatomy definition |
== Selecting files to process == == Creating a pipeline == == Plugin structure == The available processes are organized in a plug-in structure. Any Matlab script that is added to the plug-in folder and has the right format will be automatically detected and made available in the GUI. This mechanism makes the contribution from other developers to Brainstorm very easy. |
