Normalizing "Clustering Coefficient local"

Submitted by Marieke on Tue, 12/10/2019 - 14:03

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

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。

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

Submitted by hdy0115 on Sat, 11/30/2019 - 06:56

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？

During Preprocessing of Image Data, many of us face problem of Model Estimation and failed to extract significant voxels,  i raised this question on the forum of Researchgate,  i am sharing it here, so anyone facing problem of Model Estimation may find useful answers and methods to overcome this problem.   heres the Link:

请教DPABISurf关于分析结构像的问题

Submitted by mshua001 on Mon, 11/25/2019 - 08:58

尊敬的严教授及其团队的老师们，您好，我想请问一下DPABISurf这个软件能不能单纯做结构像的分析（皮层厚度、IGI、等Freesurfer指标）呢？如果能的话是不是类似于freesurfer的分析呢，谢谢
