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
Dear YAN Chao-Gan
i analyse rfMRI using DPARSF version 4.3 advanced
i get the following error when Bet begin
Dear all,
I have troubling in using the mutiple comparation correction in stastical analysis in dpabi . 1.The pic1 shows the error when I was using PT with TECE . It still happened when I changed to the latest version of dpabi or using windows10 or mac system.
Dear all:
when I use viewer in dpabi , i cannot use surface view with brainnet viewer because it showed there was some mistakes. Thanks for anyone can tell me what was wrong. Details are in the pic.
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
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。
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？
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？
