Customized TPMs/(SPM12/tpm)

Submitted by Peace on Tue, 04/17/2018 - 16:16

Dear Experts

In my understandings,  I should please replace the corresponding ones under this directory instead of replacing those under SPM12/tpm.

For example:  (Customized TPM for New Segment + DARTEL in DPARSF)

When I apply downloaded reorient mats, do I need to reorient the image again?

Submitted by Hua Yu on Thu, 04/12/2018 - 03:03

尊敬的严老师及各位专家，

 

最近遇到一个问题，就是我在用DPABI处理数据的时候，出了一些错，导致我要重新处理，但是不想再做reorient了，我按照DPABI的manual把之前的reorientmats 重命名成downloaded reoreintmats，后续我就不用手动做reorient了，可是还是会跳出相应的配准时的T1和功能图像，我是不是直接点一下下方的reorient按钮就可以啦？

 

谢谢各位老师！

/bin/bash: /bin/mv: Argument list too long (Mac)

Submitted by Peace on Tue, 04/10/2018 - 02:12

Dear Experts

I'm using the latest version of DPARSF and Matlab 2017b on Mac OS 10.13.3.

How many ROIs and subjects could DPARSF handle simultaneously?

I got following errors after smoothing. A total of 28 subjects and 138 ROIs.

By the way, the script works fine with 3 subjects during my initial testing on Mac OS. No problems on Win 10 (with 30 subjects and 212 ROIs).

Dear Experts

Here I have a couple of questions regarding the DPARSF pipepline.

How to find both slice number and time points from NIfTI or DICOM data files if they were not available at first place.

Thanks for considering my request.

Hello, after the normalization step, after the files have been moved, I get this below error. 

The folder "PicturesForChkNormalization" has been created but has not been populated. It is empty. Any suggestions on what could be the issue? Thanks.

the difference for the FDR between the Xjview and the DPABI

Submitted by daozhe on Thu, 03/22/2018 - 02:30

Hi experts, 

       I do a statistic analysis for a task-based fmri with SPM.  When seeing the results, I used the software with the Xjview and DPABI Viewer. I found some discrepancy of results between the Xjview and DPABI. when using the Xjview, there is no cluster remained when the FDR was sett at p=0.05 and the enxtended  voxels were 10. However there are two clusters remained when the FDR(DPABI) is set the q value=0.05 and the mask is the group mask.

multivaraite and bivariate GCA

Submitted by butterch on Thu, 03/01/2018 - 09:30

大家好！

我用REST跑了同一个ROI的voxel-wise multivariate GCA和bivariate GCA，结果是一模一样的。我的理解是multivariate会控制其他voxel对当前两个voxel的granger causal connectivity的影响，bivariate GCA则没有。为什么结果是一样的呢？是不是multivariate只对ROI-wise起作用？

谢谢大家！祝大家元宵节快乐~
