    老师您好:        我现在虽然在做任务态的实验,想请教您关于FDR校正的问题。我的实验是比较一组被试学习前、后脑区激活的变化,关心的是枕叶的激活。学习前单样本T检验得到激活簇A,学习后单样本T检验得到激活簇B,配对T检验后得到激活簇C。可是三个检验结果都经不起全脑或枕叶的FDR校正(即用全脑做mask或枕叶做mask,Q值取0.05)。我可不可以采用以下方法:先做P=0.05未校正,再在rest中save clusters ,分别保存P=...

    I performed an fMRI task for attention. Then using the 'con files' of all the subjects, I performed a multiple regression analysis in SPM8, with a behavioral score as covariate to identify the regions that have a positive or negative correlation with the...

    Hi, when I do two same analyses (e.g. ALFF) with two separate Matlab at the same time in the same user account, I found that it is likely that one of the analysis crashes with the other. I notice that they both produce and erase tmp files with random numbers...

    老师:       您好!希望可以请教一个ica的问题。       我一直都在做ica的处理,如果我想比较病人组与正常对照组运动网络的差异,怎么定义比较的mask,因为如果在全脑水平上比较,出现差异的地方有可能是负激活的区域,可是我只要比较正的激活的运动网络,所以比较的mask就不知道怎么选了?      另外,还是一个基本概念的问题,ica得出的具体意义怎么说,...

    你好!我们使用了DPARSFA来运行Dartel的segment和normalization ,但是matlab在运行一段时间以后总会莫名其妙的报错。我们想问问是什么原因(详见下面的error message) Operation terminated by user during spm_figure (line 278) In spm_progress_bar (line 86)         spm_figure('Clear',...

    论坛老师们: 我用DPASRFA2.1版做功能连接前的预处理,做了slice timing、reliagnment、normalise(T1像)、detrend and filter,继续做了剔除头动、全脑平均、白质、脑脊液协变量后,发现图像变得怪怪的,主要有两个问题,一是所有volume在脑外也出现了信号,二是有部分volume图像整个都是灰灰的,如图。过程中文件夹都正常生成了,后面的功能连接图也跑的顺利。 我单跑了剔除头动或剔除全脑平均等,并且用rest软件试了下,换成spm5等等,还是这种情况,...

    老师:       您好!       我用mica做了一组25个人正常对照组静息态的处理,想得到运动网络,但是感觉得到的成分都不是,是我运行的问题还是怎么回事儿呢?       参数大概选取:自动选取,运行次数是50,其余参数大致都默认
