对voxel-wise的结果做FDR校正

 各位老师,我对AD组和正常组分别做了voxel-wise,请问接下来的FDR校正要怎么做啊?

另外,我想问一下,用REST来对PET图像做voxel-wise是否可以?

谢谢各位老师!

DPARSF打开问题

 各位老师好,我是做静息态的新人,也没有计算机背景,在matlab(8.1)的set path中添加了dpabi (V3.1),spm8和rest(V1.8)之后,在command line中输入dpabi,总是出现一个web browser,然后就不动了,请问什么原因?如何处理?谢谢。(我的电脑是MacBook pro 64位)

用DPABI_V1.2_141101软件处理数据时产生的问题

用DPARSF3.1 预处理任务fMRI的时候,第一步就遇到问题,跑出来的funImg 、T1Img 里面是空的,文件整理按照静息态数据的方式,已经跑成功多次了,多次检查了FunRaw 和T1Raw中的数据,应该没有问题:
??? Index exceeds matrix dimensions.

用DPARS处理ReHo时出现的几个问题,在此求助各位老师及战友!

用DPARS处理ReHo,勾了slice timing、realign、normalise、detrend、filter、smooth,但最后得到的文件只有FunImgARWDF,没有FunImgARWDFS,请问各位老师,这是正常的么?还是哪里出现了错误。另外得到的result的reho里面有以下6个文件,
mReHoMap_Sub_001.nii
ReHoMap_Sub_001.nii
smReHoMap_Sub_001.nii
sReHoMap_Sub_001.nii
szReHoMap_Sub_001.nii
zReHoMap_Sub_001.nii

 Dear Members,

Single subject analysis

 Dear Expert,
I have rsfMRI of single subject. I have analysed by using REST, ReHo & other files have been created (please see the attached file for the list of file created). I want analyse further to get DMN. Please guide me to proceed further.

Thanks

Dear Members,

DPARSF: DARTEL SMOOTHING AFTER SCRUBBING

I have the following problem with Dartel Smoothing.  

I Applied dartel Smoothing after i scrubbed all my images by Jenkinson with a threshold of 0.3 with cutting out the bad images. 
After Scrubbing i got the images with the displaced timepoints ARWCFB. I used this folder as starting directory for the Dartel Smoothing (8x8x8).
