Can I open and check intergrade file?

 Hi,
 i don't know how to open realingment done file (which processed by DPARSF program) on SPM8 
in the other words, Can I open and check intergrade file such as realignment result or normalization result (which's already done to smoothing by DPARSF) on SPM8 program? 
 
Thank you
have a nice day! 

ica提取出的z值

尊敬的各位老师:
      我想问ica提取出来z值应该怎么解释呢?我做的是case-control用双样本t检验后选取其中的roi,再提取z值,这个指的是roi在这个大脑网络的连接强度?还是指?

Empty Mask DPARSF_V2.2_130309

Hi,

I just begin with DPARSF, but in DPARSF_V2.2_130309\Templates all the masks 91x109x91 seem to be empty.

So I replaced them by those ones of SPM8, but i prefer to signal this problem.
Thanks.

关于提取感兴趣区值的问题

老师:
   您好,我在计算完两组被试的DC之后,进行双样本T检验,把有显著差异的脑区提取出来,然后想对每组被试提取感兴趣区域的mDC值。
请问:
1.ROI的制作是用对应ALL模板中不同脑区的阈值提取脑区作为mask好还是采用以Peak点为中心的球形ROI比较好呢?
2.提取感兴趣区域是不是把每组所有被试的各ROI值提取出来,然后用SPSS统计比较两组的差异吗?可不可以对每组被试的单样本T检验校正后的cluster结果提取ROI值?
谢谢您!

请教臧老师一个审稿意见的回答

 臧老师,您好!

我一个fMRI研究收到了两个比较难以回答的审稿意见,想向您请教下:

1. 我同时记录了两组被试(假设为组A和B)、两个阶段(反应阶段 和 反馈阶段)的fMRI结果,分别对两组被试在两个阶段的大脑激活模式进行了分析。

在报告数据时,我使用了三种阈值:

针对反应阶段:组内比较使用的阈值是 FDR<0.01, K>50;组间比较是FDR<0.05, K>50;
针对反馈阶段:组内比较和组间比较的阈值都使用FDR<0.001,K>50.

Bounding box to create data with 4x4x4 voxel size in MNI space?

Hi Dr. Yu-feng Zang and collegues,
I'm Wi Hoon in South Korea. I'd like to convert voxel size of 3x3x3 to 4x4x4 in MNI space using DPARSFA or SPM. 
Could you tell me bounding box imformation for 4x4x4 voxel size (e.g., [-90 -126 -72; 90 90 108] for 3x3x3 voxel size)?

Best,
Wi Hoon

VMHC within DPARSFA pipeline

I've have a question doing VHMC within the DPARSFA pipeline. The default outputs of VHMC include both VMHC and zVMHC files. The zVMHC file seems to reflect a Z-transform of the VMHC file, performed on every voxel inside a default brain mask. However, the default mask includes the midline slice that has perfect correlation with itself.

error in DPARSFA

Dear teachers:
Added is the errors when running ‘new segment+DARTEL’ using DPARSFA. But when running ’segment‘ it can work well. Actually, I can find cfg_util in spm8. Could you tell me the reason? Thank you very much!
The following modules did not run:
Failed: New Segment
