difference between "ROI_FCMap.txt" and "ROISignals.txt"?

Submitted by Lisa_Kr on

Hello,

I don't quite understand the conceptual difference between these outputs of the Functional Connectivity option. Both have as many rows as there are time points. Is it correct that "ROI_FCMap.txt" is the average correlation between the ROI and the rest of the brain at each time point and "ROISignals.txt" is the average activation of the ROI at every time point? Also are these numbers already z-transformed or not?

 

Thank you so much for your help!

I have chosen both, I see now. ROI_FCMap is in the "Results" folder and "ROI_signals" (as well as "ROICorrelation") are in the "FunImgARWSCF_ROISignals" folder. What do these files represent?

I want to calculate a one-way ANOVA to compare FC of a ROI between different groups and I am not sure which values I should take. Basically I need a file that would give me z-transformed Pearson's correlation coefficients between the seed time course and each voxel. Is it in the output of DPARSFA?

Thanks so much!!
