DPABI/DPABISurf/DPARSF

严老师, 您好

我在尝试用DPARSFA预处理数据, 并计算ReHo, 并未定义任何ROI.

在执行过程中出错, 显示没有找到WhiteMask, 我察看了一下文件,发现BrainMask和CsfMask都有,但whitemask未生成, 不知道是何原因?

谢谢！

Hi,

How can I extract ROI specific fALFF values. I used "calculate in MNI space(warp by DARTEL)" and "normalize by DARTEL" options. Based on the assumption that the fALFF images for each subject are in MNI space, I am doing the following:                                                              

Dear Expert,

While I  was running DPARSF, I ran into this error:

老师，您好。

我在运行dpaibi进行预处理时，刚做完去除时间点后即报错，请您指点一下，非常感谢。

Hi!

Hello!!

I´m preprocessong my fMRI data with DPARSF and I had a strange result after doing "Nuisance Regression". My images are completely distorted and undecipherable. This only happen when i do nuisance regression. I would like to know why is this happening and how can i solve this. It is very importante in my work to do this step of preprocessing.

I attached some screenshot of DPARSF configuration and my images before and after nuisance regression.

Thank you in advance!

 Dear Dr YAn

i work on Alff,fAlff,ReHo and VMHC  i do this step :1-pca reduction 2-feature selection 3- classification.

my qestion if i want to do statistical analysis where can i do it ,i mean  after any step 1 or 2 or 3.

and how can i do it.the output of three step is vector in matlab.

also i need source to read about statisical analysis.

your help is appreciated.

Hi everyone,

I am working with fMRI data and processing it with DPARSFA, and then I'm analysing it with spm12. After I preprocess my images, I tryed to display them using the masks in T1imagesegment.

The problem is tthat the images seems to be too long for the bounding box. How can I fix it?

Thank you for your help,

Vera
