Hi, I have one question and one problem. TEXTAL expects map in X-PLOR format but what kind of map? One can make a number of different maps in CCP4 (simple, mFo-nFc, etc.). Which type make TEXTAL happy? I've tried to run 'Build Complete Model from map' strategy and what ever I do it seems to get stuck at: Stitching and Filtering C-alpha chains... - simply nothing happens anymore. What could be a problem? Just to mention it does build a model when I use '... from mtz' strategy.
