DPABISurf statistical threshold

Dear DPABI community,

I ran some statistical analysis on surface data generated by DPABIsurf. However, I cannot figure out how to threshold my resulting T-map when viewing it in DPABISurf viewer as it is possible in volumetric analysis (e.g. select GRF, determine cluster threshold, voxel threshold etc.). Am I missing something?

Thanks a lot!

Best wishes

Version of DPABI (DPARSFA) and SPM affects fMRI preprocessing result

Dear researchers and experts, 

As the COVID-19 forces us to work remotely, I deployed the latest DPABI (V4.3) and DPARSFA (V5.0_200401) on my personal computer. When processing using the same data and the same settings, I found the results were different than previously obtained. Here is what I did:

dpabi-VBM处理相关问题

严老师您好!

1、我已经用dpabi的做了resting state fMRI的预处理,现在准备用dpabi的VBM分析灰质体积,我用一个subject用默认参数试跑了一次(只勾选了Reorient T1*和New segment+DARTEL以及Default mask),出来的结果文件目录和fMRI预处理生成T1ImgNewSegment同一个被试名下的文件相同。我有两个问题:

①请问用dpabi VBM跑出来的T1ImgNewSegment结果和fMRI预处理生成T1ImgNewSegment是否完全相同呢?能否直接用fMRI预处理生成T1ImgNewSegment里面的内容来进行灰质体积分析呢?

②在试跑这个subject的matlab流程里有一项是Running DARTEL: Normalize to MNI space for VBM. Modulated version With smooth kernel [8 8 8],也就是使用默认模板的时候smooth kernel自动设置为8 8 8,请问意思是这个平滑核是不能调整的吗?

DPARSF处理数据的一些问题

严老师您好!我在使用DPARSF的时候总是会出现下列问题,请问是为什么?该如何处理?
Chris Rorden's dcm2niiX version v1.0.20190902  (JP2:OpenJPEG) (JP-LS:CharLS) MSC1900 (64-bit Windows) 
Error: Unable to find any DICOM images in D:\Analysis\T1Raw\Sub-003 (or subfolders 5 deep) 
Converting T1 Images:Sub-003 OK
错误使用 DPARSFA_run (line 625)

请教关于DPABISurf的一些问题

尊敬的老师们,您好!

       我想问下DPABISurf中有没有使gii文件转变成nii文件的方法,gii文件转变成nii文件从原理上来看可以转变过来吗?我想把gii文件转变成nii文件,不知道怎么实施,想寻求您的一些建议,万分期待老师您的回复!

The issue with ALFF, fALFF, ReHo and FC results

Dear R-fMRI, 

1. I did pre-processing and got the ALFF, fALFF, ReHo results by DPARSF, and then I used zALFF, zfALFF, zReHo files for the 2 sample t-test which I did in the SPM12. But there are some activation regions outside the brain, and the results look very strange. What should I do? Do these results convincing? 

DPARSF preprocessing error - normalisation

Hi Dpabi experts, 

I’m trying to use your toolbox Dpabi to preprocess our fMRI data. It is a brilliant toolbox, but every time when it approached normalization step, the error message popped out (attached at last). The toolbox was run on Matlab 2019a, MacOS Mojave.
