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.

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):

尊敬的严博士,我在用统计模块进行两个独立样本T检验时,在添加患者组和对照组后,还添加了Mean FD,性别,年龄,教育年限等协变量,但是我发现在点Run之后,并没有运行协变量,得到结果和我没有添加协变量时是一样的,我怀疑是我编辑的协变量文件不正确。例如我建立一个记事本文件(OCD.txt),假如我有13个被试,我就编辑成13行,4列;每一行从左到右以此是:性别,年龄,教育年限,Mean FD;打开后内容如下:

结果如下:DLH 0.091699 voxels^-3 before correcting for temporal DOF
FWHMx = 3.744741 voxels
FWHMy = 3.687451 voxels
FWHMz = 3.645997 voxels
FWHMx = 11.234224 mm
FWHMy = 11.062353 mm
FWHMz = 10.937990 mm
DLH = 0.092841
VOLUME = 174972
RESELS = 50.345928
尊敬的严博士,关于这些结果我不是很明白,我想了解一下上面这些结果分别表示什么意思?感谢亲爱的严博士
