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

DPABI结果呈现及矫正

老师好,我做的是精神分裂症患者和对照组脑白质FA统计分析,采用TWO-smaple T test ,并且勾选了PALM中的TFCE及TWO Tailed。呈现结果时把T2_vox_tstat导入,Apply aMASK for Additionnal Thresholding 选择 tfce_tstat_fwep文件,阈值定为0.05,没有结果,想把校正条件放宽,请教下能用生成的其他文件进行呈现么?不同的文件间的组合是怎样的?我参考了网站上这方面的视频教程和文字说明,不是很懂。

1.T2_vox_tstat 加  tfce_tstat_uncp 把阈值定为0.005,这样算是只做了TFCE校正么?这样的结果能够得到承认么?

2. T2_vox_tstat加 T2_vox_tstat_fwep 把阈值定为0.005,这样算是只做了FWE校正么?结果能够得到承认么?

谢谢

Mixed effect analysis show reasonable Group and Condition effect, but Interaction effect all over the brain even after FDR corr

Dear Dr Yan,

     I run the Mixed effect analysis using DPABI, with  the between-subject factor as Group, and the within-subject factor as Condtion. The Group effect and the Condition effect F value nii image was corrected using GRF, and several brain regions showed significant effects. However, the Interaction effect nii image showed extremely large F value (up to 6.47787e+11). After FDR correction with a q value of 0.0001, the significant voxels were still all over the brain (as Seen in the following pic).

Time Points do not match

Hi All,

I have 80 volumes, however DPABI forces me put 1 (one) for Time Points.  Later, itself gives error such that

Cannot be realingned, mismatched Time Points.

 

What can be the reason?

Best,

Mustafa

使用dpabi3.0版本中monkey date模块预处理后mask范围过大

严老师:

 

您好!我采集了一批恒河猴的功能磁共振数据,采用老师您开发的最新版本dpabi(dpabi3.0版本)中的monkey date专用模块进行的数据预处理,计算了fALFF、ALFF及REHO等指标,在处理的过程中遇到了一些问题,问题内容和图片太大,所以以附件上传了。
