in [[XDS.INP]]. MINIMUM_I/SIGMA=50 prevents the sigmas from being adjusted. This also prevents outlier rejection and geometry refinement. Since the latter may be desired it would be most appropriate to use MINIMUM_I/SIGMA=50 only after [[Optimization]] (re-cycling of GXPARM.XDS to XPARM.XDS). Prevention of outlier rejection would be also obtained by using (e.g.) WFAC1=2. | NBATCH=1 | ||

NBATCH=1 removes any basic scaling done by CORRECT (as referred to by [http://journals.iucr.org/d/issues/2012/05/00/tz5002/index.html Krojer and van Delft]). | |||
A good option might be to make CORRECT only do MODULATION correction since this is not easily available in SCALA: | A good option might be to make CORRECT only do MODULATION correction since this is not easily available in SCALA: | ||
