Dear Bernhard and Peter, as Tim describes, changing the grub loader fixes the problem. I have looked into the changes to eliminate system calls and provide a version that would work without changes to the system, they are relatively minor. SHELXE just needs to eliminate calls to system time, pity

There is now another alternative. There are platforms for packaging software with necessary libraries. PyMOL for example is available using "snap". https://www.mail-archive.com/ccp4bb@jiscmail.ac.uk/msg46623.html On 2019-10-08 06:21, George Sheldrick wrote: As explained in the attached email

Dear Tommi, With coiled coils you certainly want to use the best search model possible. Coiled coils are elongated structures and a small local inaccuracy of your search model may result in large differences (in terms of overall rmsd) with respect to the true structure. Two suggestions: 1. Try

Hi Tommi, as sent by Kay ARCIMBOLDO has a specific mode to solve coiled coils (http://scripts.iucr.org/cgi-bin/paper?cb5097). Here you can find the tutorial: http://chango.ibmb.csic.es/tutorial_coiled, it explains how to launch it through the command line and a summary explaining the improvements

Hi Tommi Yes, AMPLE does well with coiled-coils. The QUARK route is the easiest to try. In your position I would simply trim a bit of sequence off either end. Maybe you can see homologs that are a bit shorter at one terminus? In any case, that's unlikely to affect the modelling and we've seen
