Hi
How could I extract peak voxel time series?
Many thanks in advance.

各位老师和同学:
我对扫描参数一直了解不多,最近在写论文时有一些困惑,问题如下:
1. REST的旋转角记录的是标准角,请问标准角是指多少度呢?
2. T1的旋转角记录的是矢状位,这个又是多少度呢?
3. 我们数据的TR是2530(在北师大采的数据),但我看很多研究里面T1的TR是7-8ms,而另一部分则是1000-3000ms,为什么差别这么大呢?
提前感谢!
3DT1图像用DARTEL分析,灰质c1开头的文件经过“Normalize to MNI space”后出现了下图这样的图像,分析步骤也在下边,请问我该怎么解决?期待您的回复,谢谢!
求教各位老师,
我先做了某个ROI voxel wise的功能连接后,将全组人这个ROI的FC和某个认知任务的的得分做了相关分析。为什么得出的数据格式是.nii, 我以前做出来的都是.img 和.hdr两个文件?是不是哪里出错了?
谢谢各位老师指教!

Hi
I am trying to find the path coefficients between eight DMN regions and my study onsists of 8 patients and 8 controls.By following the GCA tutorial I put my subjects in a folder with "subject001,subject002..." subfolders,however, as I wanted to add the data directory the following error showed up:
Hey,
is it possible to calculate an averaged power spectrum of all BOLD-Signals in a region of interest?
Thanks,

Philips3.0被试dicom数据拷出来后,在电脑上显示没有后缀,能否使用DPARSF.或者有其他方法转换?谢谢大家了。
老师,
您好!我扫描的静息态数据是15分钟,不知道这个时间可不可以,是否时间太长?如果太长,扫描出来的数据该怎么使用?
应该先扫描结构像还是先扫描功能像,先后顺序是否会对数据结果产生影响?
谢谢,老师~

Hi
I would like to perform ROI wise (multivariate) coefficient based GCA. However, I do not know whether to set the order as "1" or "2"?
Secondly, what does the "order" represent?
Many thanks in advance.

I'm trying to detrend a set of rest images using rest toolkit,however, the following error occurs:
Exception occured. (MATLAB:nonExistentField)
Reference to non-existent field 'mat'.
