Dear all,
Thank you for the great toolbox. I am new at using DPARSF and I am still trying to familiarize with it.
Specifically, I would need to regress out from my resting state data WM and CSF signals. I did all the preprocessing with SPM12, and used DPARSF to regress out nuisance covariates from my normalized images. Everything worked fine, I just have a doubt about the output. I get txt files for each subjects, with 5 columns. My question is, as I am regressing out only the WM and CSF signals, what do the other columns of the txt files represent? Which are the columns related to WM and CSF? I wanted to merge this txt file with my movement parameters file (obtained with SPM), but as I am not sure of their meaning I do not know how to proceed with this. Moreover, are the 4D CovRegressed volumes the input I should be using for my functional connectivity analysis? Or should I subtract those from the normalized volumes?
Thank you very much!
Best,
Giulia
Hi,
Hi,
1. Please see http://rfmri.org/content/covariable-file. The last to columns are WM and CSF.
2. 4D CovRegressed are the 4d residual after regression. You can input them to functional connectivity analysis.
