vmhc疑问

想请问一下,rest做vmhc可以采用default mask吗?我看很多文献好像是要自己制作模板。由于不是原始数据,不能制作模板,可以做vmhc吗?

关于VBM分析结果的校正

大家好,最近在学习VBM分析,好多文献在报告结果的时候都写的是the cluster-level statistical threshold was set at P < 0.05 corrected with underlying voxel level of p < 0.001 at the non-stationary cluster correction,我只知道FWE,FDR,Alphasim这些

template 是不是就是mask?

有点糊涂了,是不是用imgcaculater做出来的就是template?

关于静息态数据功能连接的问题

各位老师好:

      我现在在做静息态数据的研究,先用freesurfer对数据进行处理,提取时间序列,导入matlab中,计算相关系数,进行Fisher‘z变换,如何将数据导入图像中变到标准图像中去呢?谢谢!

DPARSF & non-parametric analysis

Dear REST team:

The issue of non-parametric analysis in fMRI study was highlightened again in recent days. I'm wondering is it resonable to use DPARSF for pre-processing combined with other non-parametric toolbox (such as SnPM) for statistical analysis?

 

Best wishes,

Flora

关于voxel-wise的问题

老师,您好,我用一个AAL脑区作为ROI进行voxel-wise分析,定义好了ROI之后运行会报错,不知道是什么原因呢

possible bug

Hi there,

 I am using RestPlus to compute functional connectivity when I define my ROI using AAL atlas, it save it as a .nii file but while analysing it looks for .img/.hdr file

I am not sure why it doesnot save as .img/.hdr it gives an error and stops computation when it cannot find the file in right format.

 

Thanks for your help and suggestions.

bug in AlphaSim?

Dear REST experts,

Recently a shocking paper has been published which criticize the use of cluster-based parametric correction:

“eddy- current” toolbox in FSL.

Firstly, all the images  should be corrected with the “eddy- current” toolbox in FSL.

臧老师好,reviewer提出使用T1图像做协变量前,需要用FSL做这个步骤?呃,我手头没有FSL软件,有啥可以替代的么?
