[ccp4bb] regarding coot and loading an MTZ file

Hello, When I run coot in order to read the experimental MTZ corresponding to the PDB I am viewing, I got the following messages (attached is long lines original log): --- command: (refmac-for-phases-and-make-map /home/berenger/usr/xp_1m6t_14122009/1m6t/1m6t-sf-exp.mtz /DERIV_AU/DERIV_AU/FP

Hi Francois, your mtz file doesnt appear to have any phases, so Coot (or whoever) cannot make a map. What Coot cleverly tries to do in such a case is to use calculated phases from the given pdb (and mtz) file. So it runs refmac with the pdb and mtz to retrieve this phase information. There is

My current understanding is that 1) The new 120Hz LCD monitors are not compatible with the old goggles. Something about the type of polarization used for the shuttering effect. So if you were going to try out one of the new 120Hz monitors (~ $400) you might also want to spend on the nVidia

Hi Amit, Normally, we optimize annealing conditions with labeled DNA (cy5, FAM) - adding MgCl2 and KCl usually improves annealing efficiency. You can detect fractions of single and double stranded DNA on standard PAGE gels. We then use the same condition to anneal the crystallization reagents.
