slice timing处理数据时TR不一致怎么批处理

Submitted by runningboy on Fri, 09/29/2017 - 16:16

尊敬的严老师:

您好！最近处理一批fmri的数据，每个被试的TR不一致，有2、2.1、2.3等等，在进行到slice timing这一步时如果上一个被试与下一个被试TR不一致程序就会自动停止。我按照之前授课视频将TR设置为0自动检测TR的做法，但是matlab总是报错。希望老师能给予解答，谢谢老师。(DPARSF 4.3 basis，spm8，matlab2010b)

关于REST的Alphasim校正

Submitted by lizhe8785 on Wed, 09/27/2017 - 23:39

各位老师好，最近投稿遇到审稿人认为用REST做Alphasim校正有问题，但是FDR/FWE校正又不survive，请问有什么办法能解决。谢谢老师！

Nonparametric test and multiple comparison

尊敬的老师：

您好！我正在学习统计分析这一部分内容，作为一个初学者，对于非参数检验和多重比较的适用场景有些不确定。

具体来说：置换检验后能否进行FDR或者高斯随机场校正？

数据处理前的数据整理问题

Submitted by luluchen on Sun, 09/24/2017 - 11:53

尊敬的严老师：

您好！学生刚开始接触静息态数据处理，所以按照您教授的步骤进行操作时总是有问题，

我就在想可能是因为我的数据整理有问题，所以我希望你帮我看一下下面这段MATLAB显示的问题，

同时可以麻烦老师教授一下如何在数据处理前整理数据吗？预处理之前的数据整理有何要求？

谢谢老师，盼回复！
