What you sent has errors, maybe typos

Do
save -f -d Hold
setrmt case -a O:1.55,Fe:1.8,Bi:2.3
cp *set* case.struct_new
x clminter
x clminter -up
x clminter -dn
cp *.struct_new case.struct
cp *.clmsum_new case.clmsum
cp *.clmup_new case.clmup
cp *.clmdn_new case.clmdn
cp *.in1_orig case.in1

I do not recommend using -in1new with MSR1a. Also run a few iterations
5-8?) with MSR1, do a save then switch to MSR1a.
