Dear experts

In a statistcal analysis of DPABI, a default setting of mixed effect analysis is 2X2. 

What if I want to use mixed effect analysis of DPABI with factors greater than 2?

Dear Experts,

I am new to FSL and RS signal analysis, so I need a help to understand the methods and the results of a preliminary fcMRI study that my supervisor has been working through.

He wanted to test variation in connectivity within motor circuits at rest. It is a single group design with repeated measures, divided into three parts: baseline RS scan, task performance and control RS scan. The idea was to compare the two RS scans in order to see variation in connectivity after the task performance, thus expecting increase functional connectivity within motor circuits.

Dear DPARSFA list,

I am wondering how I can run DPARSFA with sun grid engine (SGE). Our server does not allow to run parallel processing so I was wondering if you could give advice on how I can run DPARSFA with SGE. 

Many thanks for your help.

Best wishes,

Hi there,

While attempting to run the preprocessing on the Demo Data from the fMRI course per the video instructions, I ran into a few issues. Upon hitting run, MatLab says it is launching a parallel pool to run my processing in, but also MatLab says no jobs are currently running. Additionally, it says that the parallel pool is busy, and this continues for hours, over 9 that is. I can't seem to find the file either of the altered data, so perhaps the process is just incomplete. What could be a potential problem? 

Thanks,

Hi,

I'm trying to set up an ANCOVA with covariates.  I have FD as one covarate and 4 groups (numbered 1, 2,3,4)

How do I set up the analysis.  Can I load in an FD.txt file and a file with groups listed as 1-4, or do I make a multicolumn file with 5 columns, or do I need a separate file for each group, as well as 1 for FD?  Also, how will I know from the output that the covariate has been removed from the data prior to the group F test being computed?

Thanks,

Matt

Hi, 

I'm trying to calculate ReHo on residuals images obtained after GLM analysis ("simulate" resting-state). 

Basically I just want to regress signal from WM and CSF, Bandpass filter, detrend and finally calculate ReHo. I have 2 questions
