Basic software needed to start analyzing FMRI

Hi, 

I am epilepsy surgeon wanted to start fMRI for our epilepsy cases evaluation. 

1. Which softwares do I need apart from the toolkit mentioned here. 

2. specifications of computer, ( I have windows 10). 

Can somebody help with analysis from this group? 

Rest Tools - ALFF maps

Respected Sir , 

My work is focussed in the analysis of neuroimages. I ran a group of subject fmri data with Rest tools and obtained ALFF maps . I would like to know how to obtain the alff value for individual regions of the map and  parcellating it with Automated Anatomical Labeling (aal atlas) ? Is there a way to directly extract the ROI from the rest toolbox ?

Regards,

Anannya

rest后处理的一些问题

请教各位老师:

我在用REST做extract ROIsignal时,填写了一个ROI区域,结果出来三个样本分别是0.572,0.571和0.551,我想请问信号值有没有阈值,大于多少才算阳性?还有我加入2个ROI,ResultCorr结果显示的相关系数是值得两个ROI的连接值吗?

还有个问题就是我用DPARSF跑出来的数据做power spectrum得不到谱线,但是用GIFT的结果却能得到谱线,这是什么原因?

因为我是放射科医生,对有些数学问题和处理步骤不太了解,还请各位老师不吝赐教。

用REST做AlphaSim校正,Estimate FWHM时报错!!!

我用REST做AlphaSim校正,使用Estimate FWHM时,选了统计图,选了mask,点击Run后,MATLAB中报错如下所示,这是什么原因?

未定义函数或变量"testFlag"。

出错rest_Smoothest_gui>Comput_pushbutton_Callback (line 207)

if strcmp(testFlag,'Z')

出错gui_mainfcn (line 95)

        feval(varargin{:});

AlphaSim和GRF校正

最近我用最新版的Dpabi做GRF校正,遇到一个不太确定的问题想请教您。因为最近AlphaSim校正争议很多,使得在用同为cluster-level校正的GRF时变得更加谨慎,我想问下在GRF校正中,p-voxel以及p-cluster是否可以继续使用0.01(p-voxel)和0.05(p-cluster),因为我看有些人建议把p-voxel提高到0.001更严格的水平,如果这样,p-cluster应该选择多少?
