Hi all Is it possible to input the phs file from a shelx run into an autosol run for some phase improvement with solve/resolve?? I tried putting in the HA sites but then the resultant map is worse. Also what are acceptable skews for low resolution phasing (worse than 4A) ? I understand the docs say 0.1 but does that also apply for low res?
