关于flexible factorial design的问题

老师您好:
      四组被试(三组病人,一组正常人),每个人分别有三次扫描,定义了两个主效应:group(组)和condition(代表三次扫描);一个交互效应:group*condition。采用spm的flexible factorial design设计好矩阵,想看group和condition及这两者的主效应,contrast weight分别应该怎么定义?
     期待各位老师回答

Input .img/.hdr files in DPARSFA

 Dear experts,

I wanted to seek confirmation that DPARSFA runs exactly the same way regardless of whether the input are .nii images or .img/.hdr images? In your script it seems that the code accepts both formats, but I wanted to be sure that using .img/.hdr files gives me the same result as using .nii images would.

Many thanks indeed!

Combining runs in DPARSFA?

 Dear experts,

  1. When conducting a FC analysis in DPARSFA, it seems I cannot specify two runs per person. Is this correct or is there a way to do an FC analysis using both runs in DPARSFA?

Hi REST list,

 

I am new to the fMRI and REST toolbox. I'm using REST toolbox 1.8 on SPM 8 (MatLab 8.2 R2013b, Linux Ubuntu). When I open the Slice Viewer I get the following message:

 

Slice viewer

Hi everyone
I have a question regarding the slice viewer.
I performed paired T test from the rest toolbox on a group with 6 subjects for 2 conditions.
When I overley it with the template (ch2), it keep giving me an error when I was trying to change the threshold scale provided in the viewer.
I have the latest version of REST.

Any Ideas please?

请问DCM中用到的roi能用rest提取出来的roi代替么

dcm的roi一般是在spm里面,用eigenvariate提取,我看了dcm的程序,没完全看懂,好像还有将roi时间序列detrend,白化的处理再建立模型。请问能否将rest提取出的roi作为dcm的输入呢(rest的roi有正负,而spm提取的roi只有正值)。谢谢老师!

如果扫描的slice是偶数层 slice order 和 reference slice 怎么设置?

请问各位大侠, 

如果扫描的slice是偶数层 (如30层) slice order 和 reference slice 应该怎么设置?

谢谢!^^
