Error message when running functional connectivity analysis

Submitted by krisfarrant on Wed, 11/05/2014 - 04:27

 I am trying to run a voxel-wise seed based functional connectivity analysis in the REST toolbox. I am using the HCP (human connectome project) data which has 1200 volumes and a TR of .72. When I run the analysis I get the error:

SPM8，VBM的处理分析

Submitted by shencheng on Tue, 11/04/2014 - 22:36

 请各位老师指教。问题如下：在一篇比较长期音乐训练对大脑灰质密度产生影响的文章中，提到提取每个被试发生灰质密度改变的每个cluster提取一个EVs值（mean first eigenvariates），这个值使用SPM8提取的，然后用EVs值与两个音乐判断的行为指标做多元回归。

SPM统计分析

Submitted by You.Jia on Tue, 11/04/2014 - 21:53

 各位老师好！
我想问一下，在用spm8做个体统Specify 1st-level计时，数据是不是要是任务态下的，而不是静息态的？
还有由于我们学校没有设备，所以数据都是网上下载的（ConnectomeDB），但是在设置New “Condition”时onset time不知道怎么办。是自己定义的，还是原始数据应该给出参数呢？看文献里的意思应该是刺激时的slice，是不是在参考手册中应该会给出详细任务介绍呢？
还有做统计分析究竟要得出什么样的结论呢？是要检测出任务态下的激活区吗？reho和ALFF属于统计分析吗？
希望老师给予解答，不胜感激！
