single subject paired t test error

Hi everyone!

I'm trying to run a single subject rsfmri analysis. I run DPARSF and get my 2 zFC maps , one for each of the 2 sessions (pre and post treatment). The maps look good in the viewer! I put these 2 zFC maps in the stat analysis tool by selecting a paired t test modality, in order to to get a comparison-t-map between the two. Is this right so far? The stat analysis tool look running fine and provide me with a map. However, this map cannot be seen in the viewer. When trying to upload it, matlab provides me with the following error:

Difference between "rand NW" and "permutation" in GLM panel

Dear GraphVar team,

I want to use a nonparametric test to do a group comparison, but I don't know which of the two options of non-parametric test would be apropriate. Could you explain me the difference between them? I think in my case it would be the "permutation" option , but I would like to be sure.

All the best,

ReHo中回归噪声报错

 老师您好,我现在做另一组病人的时候一跑到回归分析这一步就自动报错,说没有这个文件,可是我明明是有头动矫正后的文件的,我看了一下报错里面那个文件名称和我自动生成的名称不一样,报错里面提示无法打开rp.mrp_a20160203_132726ep2dboldTR2200GRAPPAs003a001_011.txt,可是我自动生成文件的名称是rp_a20160601_132726ep2dboldTR2200GRAPPAs003a001_011,报错名称里面多了一个mrp,但是我就算把那两个头文件重命名也还是说没有这个文件,我不明白哪里出错了呢?

dpabi error

Hi, all

About the output of VBM using DPABI

 

Hello,

I preproceed the T1 images for the VBM analysis using DPABI, and I have some inquiries regarding the output files.

I chose the "New Segment + DARTEL" option, and I got files whose prefix are "smwc", "mwc","wc1".

According to the naming convention of output files introduced in the VBM8 manual, "mwc1" seems to mean "modulated warped gray matter segments", and "smwc1" seems the smoothed "mwc1". Here, I am wondering why the smoothed files (smwc1) were generated eariler than the "mwc" files.

ROI signals and Filtering

Hi all,

I just have a quick query, so I extracted ROI time course from 6 region. At the define ROI stage I added 6 masks and DPARSFA listed in alphabetical order. Whwn i got the results in the ROI signal folder I  have 6 list (6 time course from the masks I defined). My question is are these timecourse columns in order of the the way the mask were listed, so would my first time course be the signals for the first mask of the 6 and so on).

Repeated Measures with more than 2 time points

Dear GraphVar team,

It's possible to do a repeated measures analyses with more than two time points  in GraphVar - Turbo GLM ? 

My goal is to compare 2 groups('Movement' and 'Rest') where each subject in each group has several matrices (several observations).

All the best,

Vera

请教关于mixed effect analysis问题

严老师:

    您好!我想看实验组和对照组治疗前后ALFF差异,是不是应该用mixed effect analysis?我用DPABI做mixed effect analysis后,得出的Interaction_F.nii在Viewer里显示的图像同ANOVA图像,只能看出哪些区域有差异,但是不能看出具体哪些是升高的,哪些是降低的。假设实验组治疗后壳核ALFF升高,而对照组治疗后壳核ALFF不变或降低,请问如果我想看两个组在壳核ALFF的变化不同,我该用什么方法呢?

    希望您能在百忙中帮忙解答,谢谢您!

Possible to create interface pictures and montages by script using function of DPABI viewer?

Hi,

I'm trying to generate the interface and montage pictures automatically via a script. That is, I want to 

1. Load a nifti file (blobs) onto a T1 anatomical image (like in the viewer)

2. Load a colormap for the blobs

3. Specify an x/y/z coordinate

4. Specify an overlay transparency value (i.e. want to set it to 0 )

5. Create the interface pictures automatically (and save to a folder) at the specified coordinates (just like it can be done with the "save interface as Picture" button only via a function/script)
