Questions about Interpretation of the result(GRF correction and correlation)

Submitted by DHLee on

Hello, I'm using dpabi well for fMRI analysis. 

Thank you for developing this useful toolbox. 

I have one question about the interpretation of the results in GRF correction. 

Ex) I tried to correlate some clinical outcomes with zfALFF maps in disease group. 

so, I utilized 'correlation anlaysis' function  in 'statistical analysis' tap (zfALFF maps located in 'Group images', clinical outcomes located in 'correlation seed series' for voxel-wise analysis).

Filter button after ALFF/fALFF band

Submitted by gergo7633 on

Dear Experts,

 

I'm quite new to DPARSF and try to do an ALFF/fALFF analysis to feed the results into a paired statistical test (session difference).

I'd like to know what does the blue filter button do after the ALFF/fALFF radio button and band.

If I mark it, the filter part (5 lines above) becomes active and shows the band's lower and upper cutting points in blue.

严老师,您好:
        不好意思打扰您,我是来自上海海事大学的一名研究生,最近在学习DPARSF对fMRI数据进行预处理时遇到问题,在查找资料无果后,故此写这封求助信向您求助,望您在百忙之中能够抽空帮忙解答疑问。具体问题如下:
        按照讲解设置,具体步骤在运行完Normalize后,出现错误:错误使用 copyfile
未找到匹配的文件。
 
错误使用 copyfile

problem in installation of dpabisurf(windows)

Submitted by xwf on

i followed the instruction of Doc. yan_DPABISurf Installation on Windows | The R-fMRI Network (rfmri.org)

when i finally test the dpabisurf processing by running utilities as the instruction, matlab returns:

docker : invalid reference format. 

see "docker run --help"

besides, there is no report of error during the whole process of installation. 

can anyone help ?

thanks

请教ICA数据预处理问题

Submitted by ariayang on

各位老师好,

        我想请教几个做ICA之前数据预处理的问题:

       1. 我用DPARSF做预处理,除了slice timing, realign, normalize, smooth四步外,是否要做nuiscance covariates regression? 我查的资料看到有两种说法,一种是无需回归协变量因为ICA能够分离独立信号源无惧协变量影响;另一种说法是推荐在上面四步之外加一个Bias correction,但这个Bias correction是SPM做预处理的步骤,不知在DPARSF里面是否对应nuiscance regression?
