Hello,
We recently used REST to run a seed-to-voxel connectivity analysis with
various ROIs. We are interested in extracting the correlation coefficients
for each subject so that we can look for relations with symptom severity.
For each subject, there is an ROI_FC_map.txt file. There are 12 columns
(for each ROI) and 160 rows (for each time point). However, I am confused
since many of the values are greater than 1. Are these values supposed to
be correlation coefficients (between -1 and +1)? Did we mess something up?
Thanks,
Stephanie

Hi,
Hi,
That's the time series for the 12 seeds.
You can use the Signal Extractor to extract the correlation values from the functional connectivity maps (brain volumes).
