== Molprobity not active in COOT == | |||
Q: I am using COOT 0.8.1 EL that comes with the CCP4 6.5.010 on my Mac OS X 10.10.2. I wanted to run molprobity but the Validate > Probe clashes button in my pull down menu is not active. Is this function available in this COOT version? | |||
A: Reduce and probe are separate programs available from the Richardson’s lab at Duke http://kinemage.biochem.duke.edu/. Download and install on your box. Then coot needs to be told in some instances where it can find these executables. I have the following lines in my ~/.coot file in Linux. | |||
<pre> | |||
;; .coot | |||
;; This file is required. As of coot 0.8pre no other mechanism for | |||
;; enabling probe in coot works | |||
;; | |||
;; This is full pathname of molprobity's probe program | |||
(define *probe-command* "/apps/xray/bin/probe") | |||
;; This is full pathname of molprobity's reduce program | |||
(define *reduce-command* "/apps/xray/bin/reduce") | |||
</pre> | |||
Untried: if you have Phenix installed: it comes with phenix.probe and phenix.reduce - you could insert the paths to these binaries into the above definitions. | |||
== some symmetry mates not shown == | |||
Q: This structure has been solved and refined using phenix in the hexagonal setting of space group R 3. There is one copy per asymmetric unit in R 3. As you can see from the attached image, coot is rendering some but not all of the symmetry mates. | |||
A: Turn up the radius a bit and use (set-symmetry-shift-search-size 3) . I would have thought that 2 is big enough, but maybe not in this case. | |||
