摘要： PROBLEM TO BE SOLVED: To provide a supporting system that makes NMR signals to be reverted accurately. SOLUTION: This supporting system starts the reversion of the NMR signals by reading a file of an amino acid sequence (S102). At the time of starting the reversion, the system also prepares a log file (S104). The log file contains commands which are issued through operations whenever the system performs the operations for reversion, such as the establishment of bond connectivity (S118), the preparation of cluster tags (S122), the reversion of fragments (S126), etc. Consequently, the operating course of the reversion is written in the log file as a series of operation command trains. Even when the reversion is corrected, the operating course of the reversion can be reproduced by leaving all logs in the operating course of the reversion including the correction.
