DPABI/DPABISurf/DPARSF

Please Prof. Yan

I tried to process dicom images for fmri and nrrd images for structural mri
when i use Dpabi i have problem with nrrd image
error: there is no images inside the mask file
i use this setting

Thanks for your help.

I am using the DPARSF toolbox to run through 1 subject's data as my first case.

Dear experts

All files were in NIfTI format (FunImg and T1Img)

From the error message:

Removing First 10 Time Points: Sub_001 OKRemoving First 10 Time Points: Sub_002 OKRemoving First 10 Time Points: Sub_003 OK

Dear Experts

Here is a couple of questions regarding a covariate analysis for rsfMRI:

1. For motion regreseed (as Text Covariates) -> choose mean FD value in headmotion.tsv under the the directory of Realignment right?
2. For global iFC correlation (as Covariate images)-> which files should I pick up? (FC_FunImgARglobalCWF?)
3. Gray matter portion (as Covaraite images) ->choose wc*.
4. Any suggested reading or example for ANCOVA and repeat measure setup

Thanks for considering my request!

Cheers

Hi everyone,

after preprocessing I computed functional connectivity of one cluster (one node of the DMN predefined in the toolbox: x = -6 y = 52 z = -2). I did this for 20 subjects. Afterwards I computed a t-test versus zero (SPM contrast: 1) based on the connectivity map of each participant.

Hello,

I am new to using DPARSF and have watched the videos discussing how to you use it for both human and rat data. I still had a few questions though because I still cant get my data to process properly.

1) Do we need whole brain data? (I have 9 slices spanning 1 mm per slice in our interested regions)

2) Our data is in a 128 x 128 matrix, will this cause issues when using the 96x96x30 rat brain template?

Hi everyone, I have the following problem: I tried to compute functional connectivity by using the 'Define ROI' button. As ROI I selected one of the Default ROIs (taken from Andrew-Hannas nodes of the DMN). This Region had the following coordinates: -6 52 2 (radius: 5). However, the following output in the Matlab command window does not fit these coordinates. See the following lines ...

严老师好, 

   我想请教下关于mixed effect analysis的问题。我想看下实验组和对照组治疗前后ALFF差异，做了mixed effect analysis, 其中interaction effect做出4个脑区。我又做了下每个组治疗前后各自的差异，实验组发现5个脑区，对照组发现7个脑区，这些脑区与之前的4个脑区不全相同。我的问题是，是否需要再单独做治疗前后配对样本t检验，还是重点放在interaction发现的4个脑区上就可以了？另外，mixe分析做出的group effect和condition effect意义是不是不大，是否还需要单独讨论？

   另外，提取时间序列时的“directory”应该选择预处理生成的那个文件夹呢？

   希望您能在百忙之中帮忙解答，谢谢您!

   祝好！
