如何只做种子点和某个区域（假如额叶）的功能连接

Submitted by wangkangcheng on Thu, 03/28/2013 - 20:03

 老师好，
  在rest软件中默认的功能连接的做法一般都是ROI-全脑或者ROI-ROi之间的。现在，我想做某个ROI（假如为海马）和额叶中那个部分（dlpfc，IFG，OFC）的功能连接，是不是在rest软件的Functional connectivity 选项中的Mask处user-defined mask选择上额叶的mask，然后在voxel wise处选择海马的mask？

但是，在运行的过程中出现如下的问题。

Computing functional connectivity with:"H:\multimode\analy\rest_s12003"
 
Read 3D EPI functional images: "H:\multimode\analy\rest_s12003"...............................................
 
Load mask "C:\Users\wang\Desktop\ROI_Resliced\Resliced_frontal.nii".

你好！

“在rest软件的Functional connectivity 选项中的Mask处user-defined mask选择上额叶的mask，然后在voxel wise处选择海马的mask”这个操作是对的，可以达到你想要的目的。

同意晓伟的看法，不用担心这个warning。

请你提供一下你的操作系统平台和MATLAB版本？

@鑫迪：你追查一下sprintf的Escape sequence 'm' 是怎么回事？

谢谢！
