DPARSF functional connectivity error

Hi,

 

I have the following error come at the last step of pre-processing after ROIs are being made, during functional connectivity (or even after trying the ROI making step). Any help would be appreciated! Thanks.

Error using y_ReadAll (line 60)

主效应与交互效应

严老师,您好!

    我的实验设计是关于ALFF的,分成三个被试组两个频段,在SPM中是否能同时得出组间、频段间主效应及交互效应,还是只能得出频段间主效应和交互效应?组间主效应具体应该如何计算?

如果交互效应显著,是否还需要进行主效应的统计分析?

麻烦了!

DPABI/DPARSF视频教程V2.2与DPABI/DPARSF特训营

近日,静息态功能磁共振数据处理教程V2.2正式上线。V2.2版课程主体为2017年12月13日-19日的第二届人脑连接组神经影像研讨班暨脑成像数据分析与论文撰写特训营的授课视频,加以剪辑修订,免费开放供相关研究人员学习。该版课程在内容全面性上为历次之最,不仅结合最新研究结果介绍了静息态功能磁共振的基本概念、常用计算方法、DPABI/DPARSFA使用等基础知识,而且根据特训营学员需要补充DPABI动物数据处理专题,更添加了备受关注的可重复性与多重比较矫正专题、R-fMRI动态性专题。 V2.2全部课程共10个专题已上传至http://rfmri.org/Course#Chinese,欢迎大家观看!

另外,由于大量用户反映在线教程学习缺乏互动,并且对于DPABI/DPARSF运行中的诸多报错不能得到有效解决,兹定于2018年3月24日至26日在中国科学院心理研究所举办为期三天的DPABI/DPARSF特训营(为DPABI/DPARSF国内独家授权培训)。

Please see the attached screenshot for error message.

Thanks for considering my request.

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

DPABI standalone 3.0 启动报错

各位专家号,我的旧版本 DPABI standalone 2.3 一直运行稳定,但是新版本 3.0 升级了一直无法启动(我的笔记本 Thinkpad T470P, Win 10 操作系统,Matlab的 MCR 正常安装,运行 2.3 正常),报错截屏见附件,多谢指教!

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
