关于linear detrend

Submitted by insular on Mon, 08/23/2010 - 17:54

老师，您好。
我最近在用Rest处理一批静息态数据，其中的linear detrend这一项我有一些疑问。
我记得以前用普通方法做的时候，linear detrend要用到在relign时生成的参数文件。
为什么rest的linear detrend没有提示要选择参考什么文件？
而是默认的，我要把那个文件与我的图像放在一起？

谢谢

关于bounding box

Submitted by insular on Mon, 08/23/2010 - 17:58

老师，您好。

在听您录得教程时，提到过要修改bounding box，说是spm默认的bounding box太小，并提供了一个常用的bounding box的值。

如果我们要处理的数据不是成人，而是小孩，猴子，大鼠等等，我们的bounding box又应该设设多大呢？

我们如何评判bounding box设的合不合适？

bounding box的大小是否要根据voxel size的不同而改变？

麻烦老师了.

左右脑显示问题

Submitted by sunshine on Mon, 08/30/2010 - 13:13

我将用SPM5处理得到的结果在Rest_slice Viewer中用Montage显示和在xjview中用slice view显示，出现了两种显示下左右脑刚好颠倒了，请问各位老师这是什么原因？Rest_slice Viewer不是参考xjview写的么？
另外，在SPM5中在uncorrect情况下设置p<0.05,对应的t阈值为1.8125，而在Rest_slice View中设置p<0.05,对应的threshold为2.2281。这又是为什么？

各位老师，
      我在用REST 的UTILITY的 SLICE VIEWER ， 先设好的Cluster Size 的VOXEL为5，rmm为 4， 再点CI report 后 MATLAB 报错 如下
This report is based on CUI Xu's xjview. (http://www.alivelearn.net/xjview/)

如果BOLD图像少了一幅还能够分析吗

Submitted by demonpupil on Thu, 09/02/2010 - 13:52

  老师们好：
  我们使用GE的机子扫描患者BOLD相，扫描240个时间点，33层一共应该有7920幅图像，但是有几个病人导出数据后只有7919幅图，这样能不能进行后序静息态数据处理呢，我用DPARSF跑这样的数据一跑一个错，有没有什么办法能够解决这个问题呢？
