Hi, thanks for you reply. I try to run v4.7 test case but meet an error “** ERROR ABORT in subroutine MRGVNAMS” for smkmerge.area.nctox.20050710.ys12-nc.log and " ERROR: Speciation joiner “~” is not found for speciation variable" series errors for snjreort.temporal log. Do you have any ideas about it? really appreciate your help!
