The SeisComP3 (SC3) real‐time software is widely used in the seismological community. It provides automatic hypocenter and magnitude solutions, but with limited manual processing capabilities. The SEISAN software is also well known and provides a large number of facilities with manual processing and a simple database for storage. SEISAN and SC3 share data structure for continuous waveform data but not for parameter data. The software presented here, SC2SEI, enables a simple, manual or automatic, transfer of SC3 detected events to SEISAN. Comparing the hypocenters and magnitudes, as calculated with the same data on both systems, gives nearly identical results, indicating that processing on either system is equally valid. Thus, combining SC3 and SEISAN makes it possible to get the best out of both systems.
