Nuisance Covariates Regression

Submitted by lihong001 on

Dear Chao-Gan,

 I am rerunning a dataset using a relatively older verions of DPABI _V1.2_141101 and spm8. Previously it worked well. This time the pipeline was broken several times. Now at the step of Nuisance Covariates Regression, it stopped again. For this step, for the option of Nuisance setting, I chose white matter, CSF, mask used Segment, method was CompCor with PC number of 5.  Here is the error message:

 Moving Coviables Removed Files: S0076 ok

??? Index exceed matrix dimensions. 

Error in ==> DPARSFA_run>(parfor_body) at 2674

One sample t-test with Rest 1.8

Submitted by Wei on

Dear experts,

I got some problems with Rest 1.8 while doing statistics for fALff. mfAllf-1 files are generated by Rest strictly following the course video. 

1. About mask: If I leave the mask option empty, does it mean that Rest will run the default mask or whole brain? Is there any default mask in Rest programme that I can use?

2. I use DMN mask created by Pickatlas. This mask was tested in SPM before for statistics analysis and it worked well. But when I put it into Rest, It comes back with errors.

Read 3D EPI functional images: "N:\test1\mfALFF-1"...

preprocessing for oblique acquisition of functional images

Submitted by Ekaterina on

Hello,

I would like to ask a very basic question regarding the preprocessing procedure of functional images acguired in oblique axial direction (100%). The check normalization pictures look pretty good.

I am obtaining slightly different results if those images are normalised to EPI or T1, espcially some lack of activation in the very rostral frontal areas?

Do you think that an extra step should be used during the preprocessing of oblique images using dpabi? Reorientation?

Any advice on this issue would be greatly appreciated.

Thanks,

Ekaterina

calculate functional connectivity in new ROIs after dpabi calculation

Submitted by JungLungHsu on

Dear Prof.

I am new in using dpabi and have 2 questions

1. after I define AAL ROI and finish dparsfa process, then I try to calculate a new function connectivity between new ROI_1 and ROI_2, could you please tell me how to do that ?

2. I use Matlab2012a in CentOS6.5 and latest version of dparsfa, when I run the process, every thing is ok but I finally get error message:  what I can do ?

thanks help
