Hello REST team,
First of all, thanks for the development of such a adequate software to analyse resting state fMRI data, and for maintaining it as an open source.
各位老师您好:
Rest 1.8 matlab2013b windows7 64bit 是我的电脑环境。
打开rest工具箱,在viewer功能中进行tal和MNI坐标系转换,比如坐标tal[-41,-65,37],转换MNI后[-46,-64,42],但是直接用rest_tal2icbm_spm函数转换,结果却是不一样的。请问这是什么情况?
谢谢
各位老师好!我对REST-GCA很感兴趣!最近刚开始初步学习!有一些问题不太明白!麻烦老师有时间帮我解答一下!
1、我不太理解GCA中的Coefficient- Based 与Residual-Based的区别,是不是一般默认的都是用 Coefficient- Based 方法?
老师您好:
我在使用dparsfa进行数据的预处理时,选择new segment+DARTEL进行分割,normalization的结果似乎很差,如下图所示
Hi there,
When I do 1 sample or 2 sample t-tests in dpabi with demo data it works fine but when I try paired t-test it produces following error:
Error using .*
Array dimensions must match for binary array op.
Error in y_GroupAnalysis_Image (line 58)
MaskData = any(DependentVolume,4) .* MaskData; % skip the voxels with all
zeros
各位老师,
您们好!
关于运用动态方法研究静息态功能磁共振数据,我想知道动态方法中的每个时间窗内至少需多少个时间点才算合理?有什么依据吗?
还有,计算局部一致性,也至少需要多少个时间点才可以被接受?
恳请各位老师帮忙解答,谢谢!

您好!我最近首次初步学习GCA的计算!我的ROI采用的是Voxel Wise的方式,结果出来4种nii文件类型,分别有x2x,x2y,y2x,y2y,我想问一下这里的x和y分别对应的是什么?x就是指的我选的ROI吗?
