Converting 3 Component .mseed Acceleration file into bbp format

Hi team, We could successfully run an existing bbp docker image to perform user-defined simulations (following this instructions: https://github.com/SCECcode/create_bbp_docker). We found that the simulated data is in .bbp format. Please walk us through the procedure to convert our seismogram (.mseed) into .bbp format. 

Sincerely
Dewan
