请教一下用rest做激活图的问题

Submitted by joyao1991 on Fri, 07/25/2014 - 22:24

已经用SPM8得到了单个被试的任务激活图，接下来想做组分析，有以下几个疑问：
1.（1）用SPM做组分析，在Results中选择FDR校正，p值选为0.05，再用slice viewer打开生成的SPM_T图（是否需要在slice viewer中再设置p值？）；（2）用rest做单样本t检验（base是否应为0？），再用slice viewer打开生成的nii文件，p值设置为0.05，并且在misc中选择FDR校正。
（1）和（2）两种方法是否有区别？
2.在slice viewer中得到激活图后想要保存下来用到论文中。十字架位置不同，显示的slice也不同，应如何选择十字架位置？

orientation of after DPARSFA - no ANOVA with spm8 possible

Submitted by ImKi on Fri, 07/25/2014 - 21:28

Dear all, I run DPARSFA to obtain ALFF data. I used the results (zALFF) as input in SPM8 for two way ANOVA (full factorial analysis 2nd level). I got the following error: (see below). It says orientation is not the same, but I double checked and it is ras for all subjects. Anyone who has an idea what is causing the problem and has a solution? Thanks a lot!
