问题三:他也没报错,就是显示:
ROI time courses retrieving through "C:\Users\Administrator\Desktop\a.txt".
Exception occured. (MATLAB:subsassigndimmismatch)
Subscripted assignment dimension mismatch.

这就是全部内容
Re: rest-gca
问题1:voxel wise是GC mapping,计算所有voxel与所选定ROI的因果关系,得出来的结果是一张图。ROI wise是计算所选定ROI之间的因果关系,得出来的结果是几个数。
问题2:不一定要有mask,但是有mask可以帮你把脑外的东西过滤掉。GCA就是用时间序列分析的,提取时间序列的过程不输出。
问题3:dimension mismatch通常是指matlab计算时两个矩阵元素不匹配的错误。能否提供一下matlab报错的所有信息?

Re: rest-gca
谢谢
Re: rest-gca
roi-wise要求2个以上,否则报错
