严老师您好:

        请问如何把4Dfmri转换成2维,一维是时间,一维是体素个数。我想把这个数据拿去做字典学习,更好的提取ROI。但是不知道怎么去转换这个。

Hi, 

I am trying to preprocess .nii files and extract ROI time course using AAL. However, I kept recieving this error message (top and bottom), can you kindly advise:

 

Warning: File: DPARSFA_run.m Line: 766 Column: 66

The temporary variable SliceOrder will be cleared at the beginning of each iteration of the parfor loop.

Any value assigned to it before the loop will be lost.  If SliceOrder is used before it is assigned in the parfor loop, a runtime

error will occur.

当对数据进行到去除协变量,提取ROI信号值的时候会出现Analyzing and transferring files to the workers ...>>

一部分的数据能够完成处理,但每次都会有数据卡在这,直到30分钟之后报错,处理自动停止
