● Computing System
 
ASCEM cooperates with the Core Facility of Big Data Analysis & Scientific Computing Academia Sinica (formerly ASGC) to construct a user-based integrated system of data transfer and process to cope with the huge amount of data of cryo-EM experiments. Services provided by ASGC will follow ASGC regulations, including charging schemes.
