我有30个被试的dicom,但是有些TR是3,time points是240.有些TR是2,tp 200.还有几个没有T1。各位老师这样的data该怎么处理。。。

老师,您好!我在dpabi使用过程中遇到两个问题,希望得到解答:
1、我们现有一批预处理过的数据,文件名为“FunImgARWDCFB”的“.nii”格式文件,请问1)这些数据是不是不能用于计算fALFF,而其他指标可以被计算;2)由于没有结构项的数据,是否无法得到“灰质密度”和“头动校正Mean FD值”的数据以作为统计分析时的协变量。
2、通过dpabi中的Viewer试图打开BrainNet Viewer时,出现报错如下:
各位专家:
您好,我的运行环境是 Win10 专业版 (补丁1809),Matlab 2011
我按照安装教程,首先安装了 Docker Desktop community 2.0.3 (Engine 18.09.2,Machine 0.16.1),然后下载并解压了 dpabi41docker 文件(解压后18.4G),在 load local docker 时,加载了 repositories 文件,出错显示
Error processing tar file(exit status 1): unexpected EOF
不知道问题出在哪里,麻烦指教,谢谢!
老师,您好!我用DPABI做到Normalize这一步报错如下图,请问是什么原因呢?之前做预处理都是没有问题的。但会出现隔一段时间不用,再用时就容易出现报错。
Dear Colleagues,
Hi experts,
I want to compute ALFF , ReHo and fALFF from SPM pre-processed (realigned,coregistered,normalized,smoothed,segmented) data. But when I try to do that analysis it throws normalizing error at DPARSFA step. It has produced fALFF,ALFF and ReHo even FC then after it has failed at normalize (Tried with EPI templates, T1, Dartel ). Here is my problem ; Result sets of this analyses are not fitting with anatomical sets why is that happening ? How can I fix that ?
Thanks
Abdullah
Dear Dr. Yan,
Recently, I used y_CWAS.m to perform the CWAS analyis. I have several questions about the CWAS analysis.
[p_Brain, F_Brain, Header] = y_CWAS(DataUpDir, SubID, AResultFilename, AMaskFilename, Regressor, iter, IsNeedDetrend, Band, TR)
For the annotation of "Regressor", it said "the regressors, nDimTimePoints by nRegressor matrix".
