Error in generating group mask

Hello, 

I have a question regarding to generating a group mask under quality contral. I wanted to generate a group mask for later use in paired t-test analysis, and this step is very important in this analysis. 

I watched the online courses to find out how the working directory is set up and tried the same way that was in the vedio:

为什么灰质密度用作协变量分析时用“wc1”文件,而做VBM分析时用“smwc1”文件?

老师好!

请问为什么灰质密度用作协变量分析时用“wc1”文件,而做VBM分析时用“smwc1”文件?

谢谢!

第一步一个是做"T1 Coreg to Fun",一个是做"Reorient T1*",第二步在“New Segment+DARTEL”生成的灰质、白质、脑脊液数据文件是相同的吗?

严老师,您好!

我在数据预处理中"Nuisance Covariates Regression"去除脑脊液、白质,所以通过"T1 Coreg to Fun"和“New Segment+DARTEL”这一步生成了灰质、白质、脑脊液的文件数据。

后面在做VBM中,通过dpabi默认的步骤"Reorient T1*"和“New Segment+DARTEL”也同样生成了,灰质、白质、脑脊液的数据文件。

请问这里第一步一个是做"T1 Coreg to Fun",一个是做"Reorient T1*",那在“New Segment+DARTEL”生成的灰质、白质、脑脊液数据文件是相同的吗?

谢谢!

preprocessing-pixelized image

 

 Dear Chaogan,

  I have a problem during doing data preprocessing using dpabi. The data is okay at the files under FunImgR (the first image below). However, it became pixelized starting from FunImgRC (the second image).  Any idea of what could have gong wrong? Thanks.

DICOM数据转化

严老师好:

我拿到的DICOM数据是每一个slice(比如有35个)上每一个TP(比如有240个)一个DICOM文件,一共8400个DICOM文件。老师展示的DeMo数据中的FunRaw中,是一个TP一个文件(共240个文件),请问应该如何将前面的8400个文件转化为后面的240个文件呢?

谢谢

使用dpabi view进行surface view with BrainNet viewer时错误

按教程我在overlay中添加Yeo2011_17Networks_MNI152_FreeSurferConformed1mm_LiberalMask.nii.gz以及在Load colorbar from MAT中载入Yeo2011_7Networks_Colormap_ForDPABI等文件后,点击surface view with BrainNet viewer按钮,matlab运行框显示错误,我看不到我的图像结果(说明:已事先安装好brainnet viewer):
