Hi All, there is a "Easter egg" for all BGMN users. Following Lachlan Cranswick's suggestion at EPDIC6 in Budapest, Aug 1998, I have implemented output of ShelX FCF files starting with level 2.5.0. See http://www.bgmn.de/variables.html#FCFOUT These are observed and calculated F's plus calculated phase angles. They are indented for (difference) fourier plots of the electron density. We ourself have not checked fourier plots using such output, until now. If someone makes some experience, please send me a (success or bug) report to [EMAIL PROTECTED] Thank you!
