老师：
您好！我最近首次初步学习GCA的计算！我的ROI采用的是Voxel Wise的方式，结果出来4种nii文件类型，分别有x2x,x2y,y2x,y2y，我想问一下这里的x和y分别对应的是什么？x就是指的我选的ROI吗？
我是新手，数据是Philips3.0采集的，TR2s，20层，150次采集，数据分析快到最后了老是报错，请求严老师给予指导，非常感谢！

DPARSF和rest分别是2.3和1.8
（1）使用DPARSF预处理，在rest的FC中data directory选择DPARSF生成的FunImgNormalizedSmoothedDetrendedFilteredCovremoved文件夹，报错提示There's no data or non-data files in this directory
各位老师，我提取出了AAL90脑区的时间序列，通过corrcoef函数得到了相关系数矩阵，是否需要转换成z值后再进行小世界属性的分析？如何转换？
I am trying to use DPARSFA to preprocess some .nii.gz files. I think for some reason the program is not detecting the time points correctly. If I leave the files as .nii.gz, the slice timing module will begin, and then give me this error (please continue reading after pasted content):
请教各位老师：
为什么我用dparsf预处理完的文件格式有时候是nii，有时候又是img+hdr？
之前用REST分类DICOM数据出错，提示ProtocolName出错，试着在REST_DicomSorter.m中分别改成SequenceDescription和SequenceName之后运行还是出错。
之后在DPABI->Utilities->DICOM Sorter做相应修改（改成SequenceName）后再运行，出现一下报错：
??? Index exceeds matrix dimensions.

Hi,
I'm using demo data and DPARSFA. When I choose my working directory (which has two folders FunRaw and T1Img) it does not pick up participants. But when I run then it shows. Can you tell me what's going on? If I use basic edition of DPARSF it picks up correctly.
Thanks,
Pritha
Dear experts,
I have finished running the Reho and fALFF in DPARSF. The brain regions that have significant group differences (patients vs healthy controls) seem overlap between Reho and fALFF. I would like to take a closer look at these results, but slice viewer can only have one overlay at a time. Is there any way/script that would help to overlay more than one statistical images on top of each other in Rest or Brainnet viewer?
thank you very much!
