Re: [ccp4bb] Comparing datasets with different resolution/quality

I Am thinking about this problem re a set of four carbohydrate binding proteins - all isomorphous but with different Ligands and weird solvent features.. first task was to get all sets with same indexing convention! (SoacegroupP65) That can be done at the data processing stage by giving one as the

Comparing maps sounds just like the sort of thing the Uppsala suite did. Maybe you can find an old binary for mapman or mapman2(?) or compile it from Martin Winn's github page. The closest I can find is EDSTATS which I think is in the old ccp4 gui. Best wishes, Jon Cooper. jon.b.coo...@protonma

Hi Matt, I guess that the datasets have the same spacegroup and very similar cell parameters? And that you have two similar models that you obtained by refining against the datasets? What you can do is to find out which dataset gives the better model, and is therefore better (i.e. generally

I should clarify. I am mostly concerned about the electron density map. I want to make sure that I can most closely compare the maps from two different quality structures, rather than the datasets themselves via CC1/2 or other metrics. This is more so for interpreting structural changes. For ex

2024-06-14 Thread Matt McLeod
Hi all, I am wondering what the best practice is to compare datasets that are of the same protein but different quality, for instance 2 vs. 3 A. I know that truncating the structures to the same resolution bin is alright, but the data quality in the lower resolution bins are also not the same
