    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这些校正方法,请问这些文献里这种是什么意思呢   non-...

    有点糊涂了,是不是用imgcaculater做出来的就是template?

    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!

    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...

    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 Computing functional connectivity with:"E:\depression1\sub002_detrend_filtered_Covremoved"   Read 3D EPI functional images: "E:\depression1\sub002_detrend_filtered_Covremoved...

    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...

    Dear REST experts, Recently a shocking paper has been published which criticize the use of cluster-based parametric correction: http://www.pnas.org/content/early/2016/06/27/1602413113 This paper also pointed out the bug in 3dClustSim in AFNI, which was left...

    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?

    reviewer提问,为啥一定是444的平滑? 我查了下,似乎有地方提出,平滑核的选择应该是voxel的1.5倍数,voxel是333,那么应该是4.5?
