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
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
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.
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 for 15 years until recently. As far as I understand the algorithm in AlphaSim is identical to 3DClustSim. So AlphaSim would have the same bug? Has it been fixed in recent release of REST PLUS?
Thank you in advance,
Jun

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？
各位前辈好！
我现在做了一个两样本t检验，打算在rest里面使用alphasim来估计cluster size，首先需要估计平滑核，具体界面见附件。里面需要输入三个文件才能估计平滑核，其中中间的mask file是做两样本t检验的mask吗？那其余的input statistical map和 FWHM of statistical map需要输入什么呢？
谢谢各位！
