DPABI/DPABISurf/DPARSF

Hi Dr. Yan,

When I used the "Save subjects list" in QC, there was a error:

Dear Chao-Gan,

I use the spm8, MatlabR2014b and DPSRASF basic 2.3_130615.

My analysis lasts 10 h for 20 patients. I would like add only next ROI. My question is,  who I have to choose a folder ? And sekend: do I have of defining "time point" again? I have mistake and  dparsf not responding. I've tried different ways.

Thanks in advance for your help.

Regards,

Ilona

Hi Yan,

I perfomed ANCOVA  and chose tukey as post hoc analysis to find the diffefence of 3 groups, however I don't know how to explain the results. 

An error occured when I tried to view the results of F.nii using dpabi viewer.

Hi,

It seems that I can't run DPABI properly under Matlab 2016a. When I start dpabi I get the following error and the logo doesn't show up (but dpabi starts without showing the logo): 

Hi Yan,

An error occured when I am performing mixed effect analysis using DPABI.  There are 2 groups of subjects (19 control and 19 patient) in my data and each group underwent 2 fMRI scan in 2 different times.  I chose grey matter density as covariate images and FD as txt covariates. Should I perform ANCOVA (repeat) or mixed effect analysis to see the difference between the two groups and within two patient conditions? How do I perform post-hoc analysis after mixed effect analysis since there is no post hoc analysis to cho0se in mixed effect analysis? 

Dear Chao-Gan,

Recently I have done a study which includes two datasets (30 patients and 30 controls, and 20 patients and 21 controls, respectively), and the second is the subset of the first. The reviewer required me to report the globle correlation between these two contrasts. However, I have never done such analysis before. Can I use dpabi or any other software to achieve it?

Best,

Hi,

I was wondering if it is possible with DPABI to check the quality of the coregistration somehow? I could only find pictures for checking the quality of the Normalization.

Dear experts.

I am looking for csf and white matter signal covariates and find the attached file in ...globalCovs folder.

However, the file contained 30 columns and perhaps the last three columns would be meaningful to me.

Please let me know which comumn represents csf, white matter, and global signal.

Best regards,

Dear Chaogan,

My study is to use voxel-based rs-FC measure to perform statistical analysis. That rs-FC measure was generated within a GM mask, so that FC was calculated between any two voxels within the GM.

After statistical analysis,  however, I consider that the whole brain mask, instead of the GM mask, should be used for smoothness estimation (FWHMx,y,z) with 4D residuals.

Dear experts,

I used Gissian random field (GRF) in DPABI  for multiple correction when comparing rs FC maps differences between patient groups.
