各位老师：
 我是刚接触rest-gca，对一些基本问题不太了解，希望得到老师们的指导：
 问题一：我对voxel wise和roi wise的理解和定义不太清楚，两者的具体含义是什么，
 问题二：必须有mask吗，gca就用时间序列分析不就行吗
 问题三：我运行时 Exception occured     subscripted assignment  dimension mismatch的问题怎么回事

Alphasim question

Submitted by catherine1994 on Thu, 01/17/2013 - 08:47

Dear All,

After my paired t-test analysis, I would like to use Alphasim for multiple comparision correction....however, I'm not sure about the procedure...
From what I saw in the video, it seems to be 1) set the p value in slice viewer 2)check the list of alphasim correction provided in slice viewer and 3)enter in the cluster size value, etc accordingly....
