WebJan 8, 2024 · 如果您应用过滤并继续使用更新的数据集，请通过选择菜单项Plot>Channel spectra and maps以绘制数据频谱来检查是否已应用过滤器。 您可能会注意到，滤除的频率区域可能会显示“波纹”，这是不可避免的，但希望是可以接受的滤波伪影。 WebThen use the study GUI to calculate channel metrics, and to visualize/show the power for different conditions. Stats comparisons between conditions for any of the computed EEG metrics are available via the study function. If you are new to study, download the eeglab tutorial data (the full study data) and explore that data via the study GUI.
