求助

 请问严老师:我准备用DPARSF处理猴的静息态数据,选择Normalization by using the T1 image unified segmentation。请问,如何在程序中选择猴的模版(即如何将人脑模版替换为猴的模版),谢谢。

如何解释病人组与对照组的ALFF差异脑区与全脑voxel与症状量表做相关有意义的脑区不一致?

 我们用双样本t检验做出了病人与对照的脑区差异,然后提取差异脑区的ALFF值与症状量表做相关,发现了一些脑区相关,然后我们用每个病人全脑的体素与症状量表做相关,得到了与症状有相关的脑区,然而这些脑区有很多与直接影像学双样本t检验得到的脑区不一样,这在解释上就迷惑了,是因为得到的ALFF双样本t检验的脑区不一定是跟症状相关?还是因为全脑体素跟量表的相关有太多是假阳性的相关?哪一种方法得到的脑区更有价值呢?差异的原因又在什么地方呢?还请老师们能指教。

Failed in Coregister: Estimate_ DPARSF

 
Dear Experts,

DPARSF Error - Following Detrending

We're working with the processing demo data in DPARSF and have gotten through the detrending step, but encounter the following error right after:

Error using rmdir
No directories were removed

In DPARSF we chose not to delete detrended files. Is there a way to get around this error without deleting those files?
Thanks!

ReHo是否需要regress out nuisance covariate

DPARSF中regress out nuisance covariate默认是不选取的,那么在计算ReHo或者ALFF时是否需要勾选这个选项?还是只有在FC时才需要去除脑白质和脑脊液信号?
