请教各位老师一个问题:
我用DPARSFA处理数据,选择里面的“Calculate in MNI Space(warp by DARTEL)”处理流程,先跑完ALFF,再做Filter。这样的话最后的统计分析应该是选生成的“Results”文件夹里的数据,还是要选择“FunImgARCWSF”里的数据?
还有就是,我看了一下数据处理时Matlab里面的代码,Filter时是对FunImgARCWS文件夹里面的数据进行滤波,而不是对Results\ALFF里面的数据进行滤波。这样的话,即是说Results\ALFF里面的数据是没有滤波过的?
附上代码:

Re: 请教一个问题,关于DPARSFA处理后的统计数据的选择。
我觉得有道理,写在这里跟大家分享一下,也请老师们指正。

对的。
