Hello,
We´ve been using REST to analyse resting state scans.
First we did it following the indications of the presentation, using a mask for the ROI and a mask for the brain.
Well, we finally obtained the default mode networks, as expected.

用REST做Alphasim校正

Submitted by micees on Sun, 01/02/2011 - 11:50

我用SPM处理了数据，没有进行校正，SPM8里result时只出来了FWE和none，我想使用REST上的Alphasim进行校正，该怎么做？直接用那个表可以吗？那是不是就是rmm=5,我用的FWHM是8。
另外我在SPM上看到的MNI坐标，在使用TalairachClient软件前，是不是要先进行一次转换才可以用啊？
谢谢啊，谁能回答我

请教：如何将分析后的功能图像转换回标化前的形态呢

Submitted by flysnail on Sat, 01/08/2011 - 22:07

请教各位老师：想将dparsf分析后得到的FC mapping 转换回标化前的形态，这样就可以将激活区overlay到未标化的T1WI图像上，该如何实现呢？需要注意些什么呢?

problems with slice viewer

Submitted by efine on Thu, 01/13/2011 - 05:43

Hi,

I am just trying to overlay a subject's zmap that I created in dparsfa that reflects the correlations among various ROIs over a structural image using slice viewe but get the following error message:

Warning: image_toolbox not valid

problems with alphasim

Hi, I am trying to run alphasim and keep getting the following error message: I've tried various masks. The error below was after I applyed the brain mask dparsfa created. Any help is much appreciated.

REST Version: 1.5, Release: 20101101
??? Undefined function or method 'normrnd' for input arguments of type 'double'.

Error in ==> rest_AlphaSim at 61

如何计算每个cluster里的ReHo平均值

Submitted by bgao on Sun, 01/16/2011 - 15:28

老师们，你们好！
非常感谢你们对我以前问题的回答！现在我又遇到了问题，特来求教。问题如下：
问题一：我想先确认一下几个问题：
1，我们用restsliceviewer 看图像时，把十字架点位到一个点后，这一点的ReHo值是不是montage左边的值?如value:Underlay/overlay=43/14.325 这一点的ReHo值是不是14.325？
2，我们用rest做单样本T检验时，用的smReHo数据，这个是每个image没减去1的，把Base设为1，是不是等同用每个smReHo的image都减去1数据，把Base设为0？（我看过视频了，就是想来确认一下，谢谢）
