关于scrubbing的问题

老师们好!

我在预处理最后一步做scrubbing(前面已经做完了filter,detrend和去除协变量了),然后想用插值的方法来对FD>0.5的时间点进行操作。但是在使用DPABIV2.3的界面进行操作后,发现有些被试的某些时间点没有插值成功,出现了空白图像的情况。试过插值方法用nearest neighbor和linear,时间点试过选取FD>0.5的时间点的前1个和后2个时间点以及单独只对FD>0.5的时间点进行操作的,都会出现没有插值成功的空白图像。所以想请教一下这是什么原因呢?有什么办法可以解决吗?

期待老师们的回复!十分感谢!!!

提取ROI的讯号及预处理的问题

各位老师您好:
 
我现在有三个问题想提问
 
第一个是:
我在进行Coregister: reslice的时候(调整ROI模板解析度),出现以下错误讯息
Attempted to access theOverlay(122,1); index out of bounds because size(theOverlay)=[121,237].
 
Error in rest_sliceviewer>AddOverlay (line 3281)
                            newOverlay(i,j)=theOverlay(i+abs(floor(Zset*theMagnifyCoefficient)),j+abs(floor(Yset*theMagnifyCoefficient)));

REST_V1.8 is not available for 2017 MATLAB??

After clicking Fun.Connectivity or other buttons, wrong alerts alway exist on the command window.

For example, ‘错误使用 matlab.ui.control.UIControl/set’ or '设置类 'UIControl' 的属性 'CData' 时出错:

值必须为用于定义真彩色图像的三维 RGB 值矩阵。每个值都必须介于 0.0 和 1.0 或 NaN 之间。'

Why, thanks for your attention

Degree Centrality and negative correlations

Hi,

I would like to know whether the Degree Centrality calculation is based on positive correlations only, or also on negative correlations? If I set a correlation threshold of r=0.2 will it take the absolute values of correlation and include negative correlations as well? If no, is there a way to calculate DC taking into account both positive and negative correlations at the same time? 

Kind regards, 

Anja Ries
