Question: how to create ROI mask for functional connectivity?

Submitted by Grace on Tue, 10/14/2014 - 05:12

Hi,

I am Grace. I am a beginner of the resting-fMRI analysis.
I want to use a user-defined ROI for a functional connectivity analysis.

I am wondering if you could tell me how to create ROI images with the MNI template using the REST gui step-by-step.

老师们好，用DPARSF处理数据到滤波时总报错，报错内容如下：
Removing the linear trend: E:
  Read 3D EPI functional images: "E:\DPARSF\Analysis\FunImgNormalizedSmoothed\Sub_001".......................................

  Detrend working. Wait.............

  Saving detrended images. Wait...
  Detrend over.

新手 关于使用DPARSF进行数据转换的问题

老师们好，我刚刚开始接触这个领域，所以所问问题比较浅显，你们的任何一句话对我来说都是醍醐灌顶。
我的DICOM数据属于MRIcroN的dcm2niigui 可以成功转换成NII文件，可是在DPARSF就总显示出错。
出错的内容如下：

Can ReHo analysis be used in task-related fMRI study?

Submitted by cherrychingju on Mon, 10/06/2014 - 11:18

Dear all,

    As the title I made, can ReHo analysis be used in task-related fMRI study? Also, is the ReHo value equal to Kendall's W (KCC)? If we use a significant region to be a ROI and extract its value, then this value is a ReHo value or KCC value? 

Your help will be greatly appreciated!

Best,

CJ
