DPABI/DPABISurf/DPARSF

如何使用DPARSF进行凸显你带个ROI分析，我添加了8个MASK模板，然后得到了24个ROInii图像，但是我不知道怎么办了

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?
