Web前言 前文近红外数据的预处理和平均（上）提到fNIRS是一种评估氧和脱氧血红蛋白浓度变化的方法，可与fMRI相媲美。fNIRS的不足是它的空间分辨率比fMRI差，但其优点是有更高的时间分辨率，并允许测量无法通过fMRI扫描仪测试… Using the FieldTrip function ft_definetrialyou can define the pieces of data that will be read in for preprocessing. Trials are defined by their begin and end sample in the data file and each trial has an offset that defines where the relative t=0 point (usually the point of the stimulus-trigger) is for that trial. The … See more This tutorial describes how to define epochs-of-interest (trials) from MEG data, and how to apply the different preprocessing steps. … See more In FieldTrip the preprocessing of data refers to the reading of the data, segmenting the data around interesting events such as triggers, temporal filtering and optionally rereferencing. The ft_preprocessingfunction … See more There are often cases in which it is not sufficient to define a trial only according to a given trigger signal. For instance you might want to accept or reject a trial according to a button response recorded by the trigger … See more The following steps are taken in this tutorial: 1. Define segments of data of interest (the trial definition) using ft_definetrial 2. Read … See more WebFor this, we will make use of the FieldTrip function ft_preprocessing.
