DPABI/DPABISurf/DPARSF

Hi all,

I’m encountering a problem with the FieldMap Correction in DPARSF pointing to

DPARSFA_run (line 812): „Index exceeds matrix dimensions.“

 I have 2 phase dicoms and 2 magnitude dicoms per slice and as far as I can tell the nii look ok and are saved in the correct folder.

The settings I have used are

Cfg.FieldMap.IsNeedConvertDCM2IMG: 1

Cfg.FieldMap.IsCalculateVDM: 1

Cfg.FieldMap.EPIBasedFieldMap: 0

Cfg.FieldMap.IsFieldMapCorrectionUnwarpRealign: 1

Cfg.FieldMap.TE1: 0

Cfg.FieldMap.TE2: 0

       严老师您好，我有如下三个问题：

问题一：在使用dpabi的时候，我们可以获取到功能连接矩阵，是不是文件夹Results \ ROISignals_FunImgARCWF \ ROICorrelation_sub_xx.mat吗？

问题二：功能连接矩阵为116x116，我看了下矩阵中所有的数都是不为0的，是对脑区进行全连接吗？可能会存在有为0的数吗？

各位老师们好，

Dear colleagues,

I hope you are fine. I am doing a test of rs-MRI analysis of one subject using DPABI and aftr the step of reorientation I got this message

尊敬的严教授，您团队啥时候DTI的处理模块呢

各位老师，请问TR一致，Time points不一致的影像数据可以比较吗？比如Alff，Reho，DC，用他们的Z值图可以直接contrast吗？

Hello, 

Dear all,

In the statistical analysis, we need to choose a binary mask.

What kind of binary masks I can apply? If I turn to the group-wise GM mask, it seems there're too many comparisons, leading to failure in the tfce+fwe correction (p<0.05).

Can I use the |Z|>2 of the Z map as the binary mask instead to reduce the number of comparisons?

Thanks!

Dear Dr. Yan,

I am using DPASFA v4.3 to run resting-state image, within the step : ARSWDCF. The detrended images are good, but something goes wrong after the regression.  Bellowing are the settings I used, the Detrended image, and Detrended + Covregessed .  If I put the cov_regressed images into ICA, it will produce even more weird results.   

各位老师好，我有一批影像数据，扫描时顶叶没有cover全，那么用DPABI进行流程化操作计算DC时，这部分脑区是否还是参与了DC指标的计算？如何解决这一问题呢？
