DPARSF进行预处理 到滤波时的问题。

老师们好，用DPARSF处理数据到滤波时总报错，报错内容如下：
Removing the linear trend: E:
  Read 3D EPI functional images: "E:\DPARSF\Analysis\FunImgNormalizedSmoothed\Sub_001".......................................

  Detrend working. Wait.............

  Saving detrended images. Wait...
  Detrend over.

运行DPARSF时，没有在运行别的东西，也没开网页，而且硬盘还有很大空间。我的DPARSF界面设置附在附件里，期待老师们的解答！

 I used 4-slices once a time by default to do the band-pass filtering, this can be tuned to account for big memory or small memory.

However, before processing, I need read all data into memory first, this is hard point.
What I recommend is increase your memory (much cheaper than your data) by roughly estimating the need dependent on your time-point.

Another trick is to use single data-type in Matlab, which will reduce the memory need by half.

Good luck.
