How to view the results of F.nii after ancova analysis

Submitted by gekehe on

Hi,

Sorry to bother you again. I  performed ANCOVA analysis with dpabi and obtained 10 nii images including the F.nii map. But I cannot view the results of F.nii using dpabi viewer. Some parameters of the F.nii can be viewed  in dpabi viewer overlay list (see below). 

How to add only ROI when I I finished the whole analysis?

Submitted by Ilona on

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

error when performing mixed effect analysis

Submitted by gekehe on

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? 

How to calculate the global correlation between two contrasts

Submitted by yaosir on

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,

Vincent
