DPABI重复测量方差分析时,在permutation test或后续的多重比较校正时报错

各位老师们:

          你们好!最近在使用DPABI进行单因素重复测量方差分析(ANCOVA,Repeated Measures)时,可以生成F图,但在点击DPABI重复测量方差分析的permutation test,或用生成的F图放到viewer后,做后续的多重比较校正(GRF)时均报错,报错信息如下:

voxel-wsie correlation between two images

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,

用DPABI做动态功能连接中遇到的一个问题

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?

Normalize by using T1 templates

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?

Turning of zipping to nii.gz and unpacking with gunzip

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

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:
