negative numbers for time courses

Dear R-fMRI Network team,
I am looking at the ROI Signals_ xxx which outputs the time courses for each ROI and I am surprised that some of these numbers are negative? Could you please explain why that would be the case?
With kind regards,
Catherine

Longitudinal resting state fMRI Analyses

Dear Prof. Yan,

I wold like to run a longitudinal seed-based analysis on resting state functional connectivity with DPARSFA . I am already familiar with the cross-sectional analyses with your software, but I would like to know how I can improve the analyses considering the presence of 2 time points (1 year apart) in the preprocessing. 

Thank you in advanced,

请教:关于DPABI统计中TFCE校正结果图像上出现孔洞的问题

各位老师好!

最近用dpabi统计模块做两组数据间(fALFF,reho)的two sample t-test时,使用了permutation test中tfce校正,但显示结果时发现T2_tfce_tstat图像上出现了很多孔洞,不知是哪里出了问题(如下图)?请问该如何解决?(同时计算出来的T2_vox_tstat结果图像没有孔洞问题。)

Automask Problem

Dear Dr. Yan,

I've encounted a prolem with automask generation. I know that I can skip Automask. But I am still very curious about its causes.

(1) My generated automask is like the attachment file 2 named 'automaskAfterFillCompletely.png (6.12 KB)'. For most slices, no-brain area was also included.

2d-ReHo and age appropriate atlases

Hello, Dr. Yan, are there any plans to incorporate 2d-ReHo computation in DPARSFA?

Would it be possible to include age-appropriate standard templates in DPARSFA (instead of the standard MNI template)? 

Like this one-

各位专家:

      您好,我想用 Yeo2011_7Networks_MNI152_FreeSurfer 这个模板取出 ROI 来对我的一些数据做一些分析,可是这些模板用mricrond 打开以后的样子如附件截屏所示。不知道需要对结果图或者模板做怎样的转换才可以使用?多谢指教!
