严老师:您好!
我在用dparsf高级版本(基本的也一样)处理数据时发现,同几个被试在相同的参数设置下,一个一个处理,和放到一块批处理发现提取出的ROIsignal的序列值不一样,不知道是怎么回事,请您方便时回答一下,万分感谢!

严老师,您好
我的同一批被试,有一部分在用dpabi/dparsf进行预处理时, “T1 Coreg to Fun”这步总会报错:“Index exceeds matrix dimensions.”,如果不做这一步,直接进行segment会不会影响分割效果?请您帮忙分析一下原因,谢谢!
操作平台:Mac osX,matlab 2014b
软件包:spm8/12均尝试过,dpabi V2.1
Slice Timing Setup:Sub-005 OK
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
