Bet: command not found

hey everybody,

I am trying to extract the ROI signals for a lot of objects, I used DPARSF to do so, now that I am almost finished with the preprocessing steps, I found out that since I am working in ubuntu, I had to install FSL. The preprocessing took several days to complete for me, and I need to know if my results are accurate or if I should install FSL and run the preprocessing steps again.
Thank you very much for your time.

DPARSF error !

Dear experts:
Hello,I am an intern in rfmri.Now,i am involved in a project about diabetic cognitive dysfunction,aimed at studying changes in regard to the small-world feature of the brain function connectivity network.We plan to use DPARSF to process and contrast two groups:one is type 2 diabetes mellitus patients;one is normal persons.At present,we met some trouble and know little about how to deal with it.Therefore,we turn to you for help.Here are two pieces of code.Thank you in advance.

What should my ALFF, fALFF, reHO and FC results look like after DAPRSF processing

Hi All,

I am an Intern and so I am new to matlab and DPARSF, so basically I have been given 2 sets of fmri data to anaylyze, one from an Alzheimer's group  the other  a control group.

dpabi功能连接分析问询

Unexpected normalization output

When processing my data for one subject, I ended up with a lot of noise in the FunRawARglobalCWS folder when I expected the data to be cleaner. Does this have something to do with the fact that the NIFTI files are in 4D rather than 3D? I attached a screenshot of the image below. The DPARSFA settings that I am using are also attached. When reorienting the functional and T1 NIFTIs, my process is to put in -45 and -25 to center the image on the viewer then pressing "Reorient", is this correct? Final question: can you tell me what each of the folder-names mean?

用dpabi v2.3做静息态功能连接的几个问题

严老师好:

我最近在用dpabi 2.3版做静息态功能连接,预处理选择realign, T1 DICOM to NIFTI, T1 Coreg to Fun, Segment, Normalise, Smooth, Detrend, Nuisance Covariates Regression (Friston 24, WM, CSF, Global), Filter, Scrubbing(按默认参数), FC。我的疑问如下:

1. 这些处理步骤对于功能连接来说是否有缺失或多余?

2. 因为我目前只是想做功能连接,所以想问下scrubbing是否有必要做?

3. 如果要做scrubbing,是在Nuisance Covariates Regression这步选择Head motion scrubbing regressors(按默认参数),还是像我现在的处理一样,选择Filter之后的“Scrubbing”?

Analysis With GM Volume as Covariates

Dear experts,

I am trying to perform an ALFF analysis with dpabi. I want to introduce the GM volume as a covariate in the two-sample t-test.

I think that I have to introduce this covariate in "covariate images" option in the statistical analysis, but What kind of images should I use?

I have the segmented and dartel images for all subjects, but I don't know if these images are the correct ones.

Best,

Juan
