This latter step is not necessary for CNS and SHELX output formats, which are written directly by XDSCONV. For these output formats, one might use MERGE=FALSE to keep reflections separate.

To have control over the column labels, one might want to modify the simple example above as:
 
f2mtz HKLOUT temp.mtz<F2MTZ.INP
cad HKLIN1 temp.mtz HKLOUT junk_xdsconv.mtz<<EOF
LABIN FILE 1 E1=FP E2=SIGFP E3=DANO E4=SIGDANO E5=ISYM
LABOUT FILE 1 E1=FP E2=SIGFP E3=DANO_sulf E4=SIGDANO_sulf E5=ISYM_sulf
END
EOF
 
ISYM column is important if you want to run SHARP afterwards.
 
In the case of a MTZ file that should be used for molecular replacement and refinement, the CAD step could be used to transfer the R_free flag from a different dataset to this new dataset. Alternatively, change of labels and transfer of columns can be done in the ccp4i GUI.
