What does the "warning" mean when doing detrend with DPABI
Forums
Hi, Chaogan
I'm confused by a "warning" (listed in the following) when I finished smoothing and began to doing detrending with DPARSFA included in DPABI. I wondered whether the results would be influenced accordingly. Would you please give me some advice about it? My matalab is 2013 version.

Hi DPARSFers,
I would like to know what is the units if using the “mean FD_Jenkinson” as the index of head motion—mm,degree? I checked the paper but did not find. Thank you in advance!
Any help is appreciated!

Dear Experts,
I am new to DPABI/DPARSF and am running the pipeline for first time. Kindly find attached a screenshot which shows by selected options.
While preprocessing is running, everything runs fine up until extract ROI time course, and I get following error:

Hi All,
I want to extract ROI signals using DPARSF, but the eigen values instead of the mean values of the ROIs.
Is there a way to extract eigen values in DPARSF?
Thanks,
Sai

Hi all,
Can the atlases bundled with the DPABI be thresholded in a probabilistic manner? My assumption is that they are hard segmentations, but if so, what is the segmentation based on.
Thanks,

Individual difference study AND GRF-correction
Forums
Hi, everyone!
I am doing a whole-brain seed-based functional connectivity analysis using pre-defined ROI. My aim is to find connectivity which is correlated with a individual difference data.
All of the proprocess and statistic steps were performd by Dpabi.
My results can survivive in GRF-correction (voxel p<0.025, cluster p<0.1, two-tailed, I got this from video course). However, previous papers usually use this method for group difference dectection (Z>2.3, cluster p<0.05).
Therefore, I have two questions here:

Dear Experts,
I am trying to use the DPARSF toolbox to do nuisance regression (WM, CSF, rigid-body 6) and filtering (bandpass .01 - .08) and cannot get the program to work. I have added subfolders for SPM8 and dpabi V1.1/DPARSF V3.0 in MATLAB 2014a. When I try to use the "blank template" for these two functions, I get the error:
How to answer the reviewer's comments about movement
Forums
Hi Guys,
I used the DPARSF to process the data. Now, a reviewer commented on my manuscript as following:
"There has been no control for movement-related artifacts, which are now considered essential to control for in resting-state analysis. Movement parameters are not reported or compared across subjects. Censoring movement frames is strongly recommended at an FD 0.5 or lower level (Power, 2012; Van Dijk, 2011). "
