老师,以及各位先进:
我使用rest的functional connectivity作Voxel-wise的FC之后,发现我preprossing的资料原本有170个档案(一共约80mb)
出来的zFC却只剩下大约1mb大小的一个档案,同时我的matlab window出现这些警告
Computing functional connectivity with:"C:\import\20130927\Analysis\FunImgNormalizedSmoothedDetrendedFilteredCovremoved\pd_004pre"

想要请教一下这是否会影响我的结果?
如果有的话,我应该要如何修正?

Re: rest的FC做完之後的影像數目錯誤
不影响结果。从很多个文件生成一个文件是正常的,而且,FC map的大小应该和原始fMRI文件大小不一样,因为FC map就是一个图而原来的fMRI文件有170个图。
