请教严老师关于原始数据的一些问题
严老师,在您细心的指导下目前大部分知识已经掌握了,我现在有一批数据,是关于脑梗死的病人。但是我的病人虽然都是单侧的,但有左侧的也有右侧的,我想把它们放在一起分析,怎么设计才能出去部位对结果的影响呢?谢谢严老师!

Dear all,
We have analyzed alff and falff comparing HC and OCD subjects within different bands (slow 2, 3 4 and 5). We would like to regress cardiac and respiratory information from the alff/falff maps. Could you please indicate me how to do so?
Thanks very much for your help!
Victoria
老师们好!
看了DPARSF与REST的新功能,有以下问题想明确一下,比较多,麻烦大家了!
论坛老师好!
首先感谢REST新版的发布,新版加入VMHC后,我阅读了一些相关的文献,想做VMHC在疾病中的分析,但文献中有些步骤不太懂,望大家帮忙。
1. “The residual time series for each subject was registered to a symmetric MNI template and was used to compute the homotopic functional connectivity.”
严老师,数据预处理完后为什么要做单样本t检验,同时为什么要用explicit mask?一头雾水
老师好:
我采用DPARSF BASIC2.2计算ALFF,出现下面错误:
Warning: Invalid escape sequence appears in format string. See help sprintf for valid escape sequences.

各位,我用DPARSF计算出Alff和fAlff值以后,结果的文件夹里面只有Alffmap和fAlffmap,看不到严老师视频里面的低频振幅图,是要用啥软件打开吗?请大家赐教!谢谢
Hi again,
Switched to DPARSFA and have my detrended native space images in subject folders in /FunRaw/FunImgNormalizedSmoothedDetrendedFiltered. Running DPARSF_V2.1_120101 and REST_V1.7_120101 on Matlab R2011b with SPM8. Here is the initial error:
Hi there,
关于新的DPARSF的Template Parameters的几个选项不明白,不知道具体的适用方向,有什么资料参考吗?或者麻烦老师简单介绍一下。
