DPABI/DPABISurf/DPARSF

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

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

Dear DPARSF users,

Having not used DPARSF in a while I was wondering whether anything has changed with regards to the folder structure as it seems my subject are not loading.. All my files are already completely pre-processed so I am mainly aiming to use DPARSF for some ReHo and SCA analyses.

My folder structure is:

../ReHo1/Subject001/Subject001.nii.gz

../ReHo1/Subject002/Subject002.nii.gz

../ReHo1/Subject003/Subject003.nii.gz

etc.

Dear all

I want to compare the resting state connectivity of three different age groups. My problem is that one of the groups have a few scanning parameters that differ from the other two. It is TR (3 vs 2), number of slices (34 vs 32) slice scan order (ascend vs interleaved) and number of scans (120 vs 180) that differ. 

My questions are: a) is it possible to still compare them in site of these differences?, b) how should I set up the pre-processing; three separate pre-processings or should I try to concatenate my data sets somehow? c) if so, how?

Dear Chao-Gan,

I want to make a striatum mask based on Harvard-Oxford atlas and used in my study, but I am not sure how to achieve it. I used to use Pickatlas to generate mask based on AAL. However, the nucleus accubens are not included in the AAL atlas. I will be really appreciated if you could tell the way to generate mask in dpabi.

Best,

Vincent

Hi,

how can I turn off / prevent the y_TTest2_Image function from saving the result as a nifti file?

Thanks in advance

Dear developers

Are the latest version of DPABI (V2.0_151201) and DPARSF_V4.0_151201 working on Matlab version '2014a' ?

Thank you in advance for your comment.

To whom it may concern,

We are testing the effects of different processing options on ReHo reliability and we would appreciate if one could help us clarify a few things:

1. Does it make a difference whether we perform 'Nuisance Covariates Regression' or 'Normalize' on our data set first? Also, is there a perferred way/reason why one should be perfroemd before the other?
