Folder structure

Submitted by richard.bethlehem on

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.

Comparing different datasets

Submitted by evast001 on

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?

How to make mask based on Harvard-Oxford atlas?

Submitted by yaosir on

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

DPARSFA processing sequence

Submitted by tomchanglai on

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?

rs-fMRI Preprocessing

Hi Prof Yan,

I am an undergraduate student in Singapore. I have asked you some questions before and  I would like to express sincere thanks for your helpful replies.

At current stage, I am trying to perform the following data processing on HCP data for functional connectivity analysis. I tried several tools (FreeSurfer, SPM, REST, DAPBI) and did not find an intuitive one. Now I tried RESTplus, which seems to be the latest updated one, and consider it to be suitable for my work.

Problem with conversion of EPI/T1 DICOM to NIFTI

Submitted by David on
Hi,
 
when I'm trying to convert EPI and T1 DICOMS to nifti, DPABI gets stuck in between. That is, it converts some data but then it just runs and runs without error message but not data is being converted anymore. For example I have raw dcm data from 30 test subjects I want to convert. DPABI starts and converts lets say 27 of the subjects EPI data, but it then goes on and on without converting more data and the T1 data conversion does not even start. I tried it with an older version of DPABI as well as with the latest version (V2.0_151201).
