I need to extract time series from hdr-img files to calculate correlation
coefficients for functional connectivity analysis. I am a completely
confused by the featquery results.
I selected the feat directory, and entered the mask in the functional image
space. I drew the roi in hi-res space, and transformed using flirt to get
the appropriate mask. I deselected all other options.
The results I obtained were confusing because the numbers for mean_mask_ts
range from 12000 to 12500, and the corresponding numbers from
max_filtered_func_data_ts range in the 15000's.
I would greatly appreciate it if someone could help me reconcile these
numbers, or point me to documentation that would explain them. I have
attached the relevant files.
