I'm working on a system where I need to use more than the default limit of 70 TLS groups. A quick scan of the refmac5 code indicates that the variable I need to change before recompiling is in tls.fh and called MAXTLSGRP. Before I go through the recompile and test, only to find there's another

Could the length of the path in the file names be an issue? Your dir names are very long. You also have this message in the log file: ==> WARNING: HKLIN has not been defined Maybe using file names without path may help when you have all the files in the working directory. Thanks Abhinav Sta

Hi all, I am trying to refine a structure with a PEG400 molecule using refmac 5.3. I have created the necessary library file and read it into the refinement, but for some reason refmac still quites and complains that it has come across a new ligand. I am obviously doing something stupid, bu

Can you combine the PHIC and FOM from each of your solutions, then do the Phase comparison in Clipper utilities checking for alternate origins? That gives a good indication of what is going on. Do you have more than one molecule in the asymm unit? You can finish up with A_phaser matching one

2007-08-08 Thread Das, Debanu
Hi Yvonne, Were you able to check the polydispersity of your highly soluble protein sample by DLS? Non-monodispersity could result in reduced propensity for crystallization. Another thing you could then try is something like the "Optimum Solubility Screen" which basically involves buffer

Hi Simon You didn't say whether you have just 1 mol/a.u. or more than one. In the latter case you can get the effect you observe because as well as considering possible origin shifts you also have to consider the possibility that say the A and B molecules have been switched, i.e. like the origin

There might be many reasons.. Do you have a spacegroup with alternate indexing? If so the two crystals may not be using the same convention. See $CHTML/reindexing.html for more details. Or is one data set a high resolution pass and one a low resolution pass? Sometimes then there are saturated
