[ccp4bb] EM maps

2024-03-08 Thread Dean Derbyshire
Hi, I'm almost certain this has been addressed before so apologies... but is there a trick to import EM map files into COOT, it keeps crashing when I've tried. Ta muchly in advance Dean To unsubscribe from the CCP4BB

maybe a silly question it there a data base or other way to tell what detector was used to collect historic data. Image header isn't hugely helpful ESRF is all I know for the source but I'd like to know what the detector was at the time... - I'm talking 2005-2010 Dean Derbyshire

Perhaps (most likely in fact) this has been asked and addressed in the past: is there (or will there be) a way in COOT to 'build' ligands from scratch? Currently I go through a long winded route of Sketcher... importing and pulling the coords around to fit electron density... then finally
