Dear admin,
I am from University of Hong Kong and we cannot access metlin database, the website showed "We have detected abnormal behavior from this IP address/User ID, and have temporarily blocked access for some period of time." Grateful if you can help to check if there are any problem pls.
Ronald
You probably need to find an internet connection where you can contact the METLIN people directly through: https://xcmsonline.scripps.edu/landing_page.php?pgcontent=contact
