GRETNA: Cannot find T1 image

Dear GRETNA experts:

I am using the latest GRETNA 2.0 with Matlab 2017b/SPM12 for Graph Theory Pre_processing.

OS: Ubuntu 16.0.4

Please see the attached screenshot for error message.

Thanks for considering my request.

Best regards

dpabi 3.0 使用小bug

严老师:

              感谢严老师辛勤付出,老师一直辛苦更新软件版本,方便我们这些普通使用者的学习使用。我最近跑任务态预处理时,发现使用dpabi3.0时,每次都是从原始数据转为nifti数据时,都是转换后,有个别被试的转换后的数据,被留在了funraw下被试的子文件夹下,即和原始数据在一起,funimag下没有相应的被试子文件夹。但是当我换为dpabi1712上个版本时,预处理就无这种错误。我使用的是spm12. 不知道这是什么原因? 是不是新出的版本兼容不好,但是我试了好几次都是i这样。

谢谢老师!

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)?
