关于配对T检验的问题

严老师,您好!

请问:1. 在dpabi统计中配对T检验的计算方法,是用添加的第一组数据减第二组数据,还是第二组减第一组?

2. 我在做双样本T检验和ANOVA检验时用的都是smALFF和smReHo的结果数据,这可以吗,还是说用mALFF和mReHo数据更好一些。

数据分析报错,请求帮助

严老师,您好,我是学习fMRI数据分析的新手,刚使用DPARSF进行分析数据的第一步就出错了,烦请严老师指点看是哪里出了问题呢?万分感谢!

错误使用 y_SCA (line 235)

严老师,您好!

Signal extractor tool question about input

Dear Expert:

I am trying to extract the  time-course signals using DPABI's signal exractor tool for a single subject event-related run that has been pre-processed with SPM. My question is as follows: 

Would the signal extractor tool work for an event-related run? if so, should I enter the 'con.nii' files or the spmT.nii files?

I would really appreciate your  expert guidance,

Best,

Catherine
