the criterion of remaining subjects,afeter scrubbing

Dear all,

I want to use the data preprocessed to do the later analysis such as build a martix. But some subjects has limited timeseries when I finished scrubbing,which may result in a strange result. So I want to know how many time timeseries left in a subject( for my case ,the total time series are 180,first 5 were revoved at the very beginning part) is enough for further analysis.

Sincerely,

Lin

对于我的三个f test,选择conjunction的时候是没有显著性差异体素的,但是选择intermed和global的时候是有的,但是不知道什么意思

下面是选择global的时候的效果图

Normalize by dartel,what is the standard template?can i change it?

Hello pro Yan,

The article with data processed by dparsf was returned by the editor

And the reviewer asked us to re-do a rest-state analysis,and set the voxel size into 2*2*2 mm(3*3*3 previous by default) to map our activation analysis

Bur the results were strange and unreasonable

So i checked the normalize results,it seemed that i can not change the voxel size

Here are two normalized results for  one identical participate

关于Nuisance Regression的问题

各位老师,

           您好。关于Nuisance Regression,Dpabi教学视频是在normalize 前做,但是还是有许多文献是放在最后做。这两者区别很大么?最好选哪种?

谢谢。

请教一下用TFCE校正后结果查看的问题

视频里,严老师应该是教大家在VIEWER里导入_vox_tstat.nii这个文件,如果通过APPLY MASK功能加上_vox_tstat_fwep.nii,阈值卡0.05就可以查看最后保存下的团块。但是这时候在VIEWER里面的取值(标尺)都是P值的范围,也无法分辨存活的团块是正性激活还是负性激活,无法直接用于报告结果。

请问各位老师应该如何解决?如何在t图上显示TFCE后的结果呢?

分别用1.5T和3.0T MRI采集的数据,用standardization处理后可以比较么?

请教一下各位老师,DPABI里面提供了一个用于多中心研究的standardization的工具,我有一批分别用1.5T和3.0T MRI采集的数据用该工具处理后,可以进行比较么?
