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

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?
