    请问三组被试通常先做ANOVA,如何在SPM里算post hoc two sample T test?

     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。 请问此处的EVs值是什么意思?有什么作用?用SPM8如何提取?

     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?...

     各位同學老師好, 有一個問題想要請教大家,我利用DPARSF etract ROI TC時會產生一個ROITC的new folder看網路上可以將其中的ROICorrelation_FisherZ.mat (node數xnode數),可以作為放進NBS裡分析的data。我想要做一個AAL90一樣的fc matrix,但是extract ROI TC時得到的是90x(200x1)[AAL90x時間點]的mat檔,而不會得到FisherZ.mat,...
