Tue, 06/28/2011 - 16:46Qiang严老师好： 我同您请教一个有关同一批受试者在不同时间点接受rfMRI检测的问题。应该如何分析会比较好一些。REST好像没有重复测定的方差分析，在分析VBM 时，有的文章使用前后两次时间点相减得到新的差异影响，然后比较差异影像在正常和患者的差别，不知Reho，FC和ALFF等指标可不可以使用这种分析。 谢谢，期待你的指教！5805 reads

Thu, 06/23/2011 - 19:35Champagne各位老师好，请教两个关于ALFF的问题，谢谢： 1、我查看了REST里面的ALFF源程序，计算能量谱 = 2 * 频谱的平方 / N，请问这里为什么要除以N？ 2、左西年老师的文章《The oscillating brain: Complex and reliable》中Fig1和公式（1）提到ALFF是Sum of amplitudes of PSD，而源程序里ALFF貌似是Mean of amplitudes of PSD，应该以哪个为准？9543 reads
