Hello,

I am interested in correlating the default mode network and the right fronto-parietal (executive) network during rest.

What I did was extract the time series of the default mode network as a whole based on a template for each subject. I did the exact same process with the right executive network using 3dmaskave.

Then I used the following 3dfim+ command to correlate the two time series.

3dfim+ -input1D ${subject}.DMN_rum_timeseries.txt \
-polort -1 \
-ideal_file ${subject}.REXE_rum_timeseries.txt \
-out Correlation \
-bucket Corr_${subject}_rum_DMN_REXE+tlrc

Does this make sense? Also, I wanted the correlational value for each subject to be saved in a file but it does not appear to be doing so. It only prints it on the terminal. I want to be sure that my .txt file under "input" is being read correctly. The input file is a single column on numbers similar to my ideal file text file.

Thanks,

Emily
