[ccp4bb] QTMG can not recognise phosphate carbon bond

2020-09-09 Thread Khushboo Patel
Hi I have a ligand with phosphate that works well in coot and pymol but when I open it in QTMG it shows phosphate as a separate moiety than the rest of the ligand. There are two methyl groups attached to the phosphate but those bonds are not visible too. so the whole compound looks like there are t

Hi Eike, one of the points is that, only because you got used to a certain operation (over many years after someone showed it to you), does not mean it is intuitive. This could be judged by e.g. showing an ignorant user both methods and let the person judge which one is easier to use... Cheers, T

Hi Tim, I don't think that metaphor is quite correct. To me it seems that no matter what button you pushed you got coffee. In my opinion intuitive software is a blessing and should not easily be disregarded. But as I said before, I am happy to read into new stuff. Also there seem to be mixe

Dear Tim, I really like your example. Has anyone of the disappointed users asked how to do it properly? Maybe it is just as easy. I think it's also up to me to do it properly and put more effort in it. Often we are restrained in time and improving your toolboox in an unexpected manner is ha

[ccp4bb] COOT v. 0.9

Dear all, after the plethora of complaints about v. 0.9 when compared to v. 0.8, I would like to argue in favour of the new version. I find RSR is now much more robust, with a larger radius of convergence, with very useful tools like tandem refinement, etc. which are particularly useful with cry

Dear Georg and others, if I followed the thread correctly, the coffee story should really go like this: for years you have been pushing the button of a machine showing a cup with a black liquid inside. After ten years, the manufacturer of the machine tells you: "Sorry guy, it is not coffee what

Dear Paul, I fully agree with Georg and the others. As I said in my first reaction, with the new coot, the inhibitor or side chain often does not end up a little wrong, but goes off completely in the wrong direction, which makes me wonder whether I had somehow selected the wrong map. It might a

Dear Paul, people are complaining that they have issues fitting their model in real space using coot 0.9.x. Personally, I very briefly used coot other the last months but also have problems using RSR properly because I'm used to do it the way it was over the last 10 years. This might be due to

Surely an opportunity for machine learning to make a real difference?  There's enough data in the PDB by now, that you can conceive of a classifier generating the most likely set of restraints appropriate given an OMIT map. On 09/09/2020 11:37, Eleanor Dodson wrote: I know how difficult it i

I know how difficult it is to get the chemistry right, and that really has to be up to the researcher.. a database of high resolution structures with metals would be useful as a sanity check. Robbie mentioned MetalPDB (http://metalweb.cerm.unifi.it/). E On Wed, 9 Sep 2020 at 11:18, Garib Murshu

Hi Eleanor, Obviously I agree that people should use restraints for metals. It will make metal refinement easy and coordination consistent with chemistry For distance and angle restraints there is an external distance restraint mechanism. PDB-REDO can generate for some of the metals. Unfortuna

Dear Paul, sorry for the delay. I did not answer your previous questions in detail, because going back to coot 0.8 did solve the problem for me, which kept me busy. But of course, to do sth. about the situation you need to understand a lot better what is going on. What I have is a “phenotyp
