DPABI/DPABISurf/DPARSF

Dear R-fMRI team,

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

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:

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？

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. 

Hello teachers!

I still can not use PLAM when analyzing FC in ROIs,in DPABISurf Viewer,I have results if  the P value is equal to 0.05,but no one in the 0.01.

Can I report this kind of results?If I only focus on the default mode network in both volume and surface space ,how to deal with it?Or ueing the mask of Yeo 7 networks is enough?

Thx a lot.

Dear Professor

When I use slice view to do correction no matter which one I chose (FDR or GRF), It always report errors. Please see the figures attached. Could you help me find out what's the problem is? Thanks

My best,

Hi 

I have a trouble uploading the data direcoty on DPARSF for doing some processing. Even though I watch the course, I could not get why I can not upload the direcoty and have the list of subject's folder in the assigned window. 

At this time I have all preprocessed rsfMRI data and just want to get ALFF/fALFF/ReHO stuff. 

Can you please let me know first of all if I can you DPARSF for just this purpose with not doing preprocessing and just ALFF/FALFF/ReHo stuff?

Dear professor 

The fMRI were processed via DPABI surf, and Alff and Reho results were acquired. However, the errors occurred when statistical analysis was conducted.

Could you please help deal with this issue?
