@Carl Love 

Thank you for your reply. 

The error message is "Error, (in sos2sdp) invalid arguments for searchtext |multivsos/multivsos.mm:260|", and the procedure and/or command that gave the error message is from https://gricad-gitlab.univ-grenoble-alpes.fr/magronv/RealCertify/-/blob/master/multivsos/multivsos.mm

So how to make it work?

Thanks a lot!
