reorient

 Hi,

I downloaded T1 data from OASIS and tried to perform VBM analysis. But I found that T1-images are with "wrong" x, y, z direction (see attachment). How can I convert them to the conventional direction (like the template in MRIcrion). 

Thanks!

How to determine REST AlphaSim parameters properly

Dear Experts,

I have read a lot of the supporting documentation related to REST AlphaSim, along with many posts in the online forum; and although I feel I have a good understanding of the procedure I have two outstanding questions which my reading has not answered. I'd really appreciate your help in these matters.

dparsf提取协变量报错

大家好,我们有一批数据在完成所有预处理后,使用dparsf做功能连接提取协变量无法进行下去。报错信息如下,向论坛里各位请教。

关于功能连接密度

 请问各位老师,1、功能连接密度(functional connectivity desity,FCD)包括localFCD、globalFCD是用哪些软件可以计算?
2、rest里的degree centrality是用来计算什么的,跟FCD有什么区别?

提取协变量出错

论坛里各位老师和同学,我是静息态数据处理的新手,在医院采集了一批病人数据,准备做静息态处理,使用的机器是飞利浦1.5T,采集到的数据并不是每个TR一个文件,而是一层一个文件,文件命名不规范,我们能够顺利的完成从格式转换到smooth的所有预处理,但是使用rest做功能连接提取协变量无法进行下去。我们猜测可能是数据的原因,报错信息贴在下面,我不是很明白这是什么意思,向论坛里各位请教。

Questions about AlphaSim correction

严老师您好,

      我在做AlphaSim校正,遇到一点疑问,如下。

how to extract ALFF-values?

Dear all,

i am working with the REST toolbox V1.8 and i would like to know how i can extract ALFF-values out of a cluster which occured in a statistical result map. I need the ALLF-values from all the voxels inside this cluster of all my subjects.
 
Thanks for your help,

Marius

2nd-level analysis

 各位老师:
       我刚开始接触SPM,请教一个问题:我在做个体水平分析的时候,设计矩阵使用了条件A和条件B两种条件,在点击result时设计了A-B的contrast,同时也做了B-A的contrast,现在做组水平分析时,选择了one-sample t test,发现最终的F检验的结果,两种条件下激活区域是相同的,请问这是怎么回事啊?问的可能比较低级,请见谅!
