Hi,

 I am trying to calculate the correlation between two image datasets and perform the permutation test. Is it possible to calculate the voxel-wise correlation via DPABI?

Thanks,

按照教学视频，在Utilities模块ROI signal extracter中添加患者组zVMHC文件，define ROI选择了view模式时保存下来的的single cluster的T2.nni文件，然后提取出现如下错误，请老师帮忙看一下

Dear

I have a problem with realingment error that is driving me crazy.

The error that occurred is as follows.

最近用使用严老师的DPABI中的TDA模块做了动态功能连接，在查阅了文献后发现很多文献在fisher-z变换后将z值划分为（<-0.5）（-0.5～-0.25）（-0.25～0.25）（0.25-0.5）（>0.5）这5段以验证sliding window对组水平差异的影响。请问在DBAPI的工具中能实现吗？

Hello all,

I am using DPARSF to preprocess some rsfMRI data for use in a machine learning algorithm. I am worried about the use of DARTEL because of overfitting resulting from the creation of a template based on all subjects. I was thinking of using DARTEL but with a template derived from an independent sample of 555 healthy control subjects of the IXI-database. I already have this template. To use, I believe I would need the hidden option mentioned in the videos "Normalize by using T1 templates". How could I go about using this option?

Hi,

since gunzip with Matlab is ultra slow I would like to turn of zipping the files when using the T1 DICOM to Nifti and EPI DICOM to Nifti option. How is this possible?

Thank you in advance

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:

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！

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！
