statistical manual

I'm new to dpabi. I find it a very interesting tool.

Is there anywhere a manual for dpabi?

Specifically I need help as to the statistical analysis. 

I saw the course, but there is no details there as to how to insert covariates (format ect), how to correct for MC, what are the implementation of using the different files created (z, m, ect)

Any link to clear descriptions will help

 

Thanks

Hi DPABI team,

DPABIsurf QUESTION

Hi DPABI team,

Normalizing "Clustering Coefficient local"

Dear all,

I want to normalize the local CC. In contrast to the global CC and global and local characteristic path length, however, I encounter the following error:

"Normalization error: some metrics derived from random networks result in zero which cannot be used for normalization."

Is there any way I can solve this? When  I look into the MATLAB file, the file truly contains several zeros. How is this possible?

Thank you so much!

Best,

Marieke

Dear all REST experts:

normalization problem

老师们好:

我按照严老师的dparsfa 的V4模板参数跑了rs fMRI, 没有报错。但是跑完后进行QC的时候发现有几个被试的配准特别差,如下图。我查了他们的静息态和T1都没有问题,想请问一下为什么出现这个问题?是否能纠正以及如何纠正?

 

恳请老师们能予以帮助,谢谢各位老师。

老师好,检查配准是否准确时,怎样调整结构像的亮度


我目前处理的大鼠数据结构像比较暗,不知怎样在DPABI里面调节亮度。

consulting the CAT12 and VBM analysis of DPABI

Prof. Yan,

                 Hei, I want to consult that whether the VBM analysis of DPARSF Advanced Edition in DPABI_V4.2_190919 is based on the processing step of CAT12 of SPM12 ?   

reho和falff结果

跑了一些没有T1的数据,得到了reho,falff。奇怪的是总是皮层大面积“激活”,其余部分都是“负激活”。也看不到默认网络。请问这种情况应该从哪里找原因呢。谢谢

有一些被试voxel size是1.8 1.8 5,这样的被试平滑核设置为多少才合适呢?
