怎样向nii文件写入数据

Submitted by yubing on Mon, 07/29/2013 - 05:41

请教，用怎样的代码把一个nii的数据或者一个dataset的数据写入nii

例如，有一个AAL分区与统计值对应的矩阵，怎样的代码可以将统计值按照对应的分区值写入AAL模板,形成一个新的AAL文件？

请求指教，多谢！

degree centrality 添加数据文件夹时报错“Index exceeds matrix dimensions.”

Submitted by xuercan on Sun, 07/28/2013 - 10:12

degree centrality 处理，添加被试数据，被试文件夹为40个，报错如上。
后把文件个数改为30个，也报错。请问这是什么原因。

Can't warp masks to individual space

Submitted by aperry on Fri, 07/26/2013 - 10:06

Hello,

I am performing resting-state analysis on a elderly population. So I have to make sure the masks (ROI, Brain mask etc) fit to each subject. I don't want to use DARTEL, but rather have a subject-specific template.
