亲爱滴们:
今天碰到这样一个问题,焦头烂额:
由于这批数据需要手动配准,所以我的处理流程如下:
1. 用dparsf批处理至realign。
2.用spm做coregister.
3.用AFNI转换格式后做Normalize
4.转换个格式后,将得到的EPI相文件放入FunImgNormalized文件夹。
然后启动dparsf,
先跳过Smooth做的ReHo,很顺利,detrend, filter, reho...没有任何问题。
然后继续用dparsf做alff以及falff,操作过程如下:
-matlab下输入dparsf
-依次去掉smooth前所有的勾
-选择工作目录
- 输入时间点190
- 选择自定义模板

hi,
the previous error i brought up was fixed by adding the line
"rest_Fix_Read_Write_Error"
before initializing dparsf.
however, the time between pressing the bottom "run" and actual data precessing is much longer in the linux environment than windows (just now i experienced a 15 min lag).
so is the time for data precessing.
what might the problem be? how can i fix it?
i'm currently using double systems on my laptop, which are windows XP and linux fedora ver 12.

Error in functional connectivity analysis when using DPARSF or REST
Forums
Taxonomy upgrade extras
Hello, Dear DPARSF team
I ran into some problems when I try to compute functional connectivity when using DPARSF. It gave me error message as following. I tried REST to do FC analysis and got same error message. And it is apparently not due to different preprocessing because I used DPARSF to do the preprocessing. Would you please help me solve the problem? Thanks a lot for your help in advance.

bug report: "DICOM to Nii" when dealing dicom files from GE under linux AMD64
Forums
Taxonomy upgrade extras
Dear RESTers:
Recently I used DPARSF to process some functional images obtained from GE HDx 3.0T system, my environment was Ubuntu 9.10 AMD 64 Version, Matlab 2009b, SPM8 and DPARSF 100510.
During converting Dicom to nii step, the system keeps running but nothing was converted from dicom files.
Maybe it's a bug of DPARSF with linux, all the images were smoothly process in WinXP.

DPARSF 做到 smooth 的时候报错

我利用 DPARSF 来预处理我的功能像数据,每个患者有 3 个 session,因此我将 FunRaw 里面设置为 subject001_1、subject001_2、subject001_3...,而T1Raw里面相应的放上 3 个 subject001 的 3D 结构像、然后 subject002...
前面的步骤运行顺利,但是到 smooth 的时候,报了错,并且文件夹中未生成用于检验 normalization 效果的图像文件夹。
系统为win xp,spm8,刚更新了DPARSF 和 REST1.4,报错信息如下:

通过患者组和正常受试者组的双样本 T 检验,找到了一些患者 ALFF 出现明显异常的区域。现在我想做这个明显异常区域中的 ALFF time course 与临床指标之间的相关性分析,我的做法如下:
- 利用 add recursively all subfolders 加入了每一名患者的 detrended_filtered 静息态图像
- 使用 user defined mask file 添加进一个我利用 rest slice viewer 保存的 ROI 图像。

我注意到我的 DPARSF 在计算 ReHo 的时候,在 Matlab 的命令窗口给出了这样的信息:

没能预定到听课的座位,非常可惜,还好有新的视频教程,看了两遍后试着处理了一下目前的患者数据,把自己的步骤和过程放上来请大家看看,是否存在什么问题。
