Or use pointless on the INTEGRATE.HKL file (not XDS_ASCII.HKL) and then SCALA -- we had one SAD case where this aided structure solution significantly, just beware that the unit cell is not postrefined by the CORRECT step then.

I usually iterate the INTEGRATE and CORRECT steps until the values in GXPARM.XDS converge. I couple of cycle are usually sufficient. With the JOB-card set to "INTEGRATE CORRECT", this is easily done with a few shell commands, e.g. to run 5 cycles:

for i in $(seq 5) ; do
   mv GXPARM.XDS XPARM.XDS
   xds_par
done

once you have gone through the whole process once. This would provide you with postrefined cell parameters.
