Question Posted 02/18/16:
Dear ADNI experts,

We have some resting scans downloaded from your website and try to preprocess them with fiedmap correction. One information we are not able to locate is the effective EPI echo spacing (ms). Would you tell us where to find it or other information that we can use to calculate it?
