DPABI/DPABISurf/DPARSF

Dear Dr. Yan,

When I was computing CWAS, I found data should be resample  to voxel size of isotorpic 4mm. But after all preprocessing, all data had changed to 4D which can't be resliced by dpabi's function "Image Reslicer" correcttly.

Or can I set the voxel size to [4 4 4] in Normalize step directly and skip the last resample after all preprocessing? Looking forward to your reply. Thanks in advance!

1. Open DPABI_VIEW, and load your images and setup.

Hi, Dr. Yan, When I regressed covariates of 200 subjects using latest DPARSF,  an error was shown as below. However, it was fine when I computed just two subjects.

Hi,Chaogan,

I came across an error when I was using CWAS in DPARSF2.3, How to solve this problem?

Looking forward to your reply. Thank you in advance.

Hello everyone,

Hi everyone!

I'm trying to run a single subject rsfmri analysis. I run DPARSF and get my 2 zFC maps , one for each of the 2 sessions (pre and post treatment). The maps look good in the viewer! I put these 2 zFC maps in the stat analysis tool by selecting a paired t test modality, in order to to get a comparison-t-map between the two. Is this right so far? The stat analysis tool look running fine and provide me with a map. However, this map cannot be seen in the viewer. When trying to upload it, matlab provides me with the following error:

Hello,

I preproceed the T1 images for the VBM analysis using DPABI, and I have some inquiries regarding the output files.

I chose the "New Segment + DARTEL" option, and I got files whose prefix are "smwc", "mwc","wc1".

According to the naming convention of output files introduced in the VBM8 manual, "mwc1" seems to mean "modulated warped gray matter segments", and "smwc1" seems the smoothed "mwc1". Here, I am wondering why the smoothed files (smwc1) were generated eariler than the "mwc" files. 

Hi all,

I just have a quick query, so I extracted ROI time course from 6 region. At the define ROI stage I added 6 masks and DPARSFA listed in alphabetical order. Whwn i got the results in the ROI signal folder I  have 6 list (6 time course from the masks I defined). My question is are these timecourse columns in order of the the way the mask were listed, so would my first time course be the signals for the first mask of the 6 and so on).
