*Q to ccp4i2dev..* Hello,
I’m not sure whether this is a refmac issue or a ccp4i2 issue but we have recently solved the structure of a protein which appears to be twinned in the space P43 with 10 molecules in the asymmetric unit. When we run refmac normally it proceeds happily and refines the structure but when we include the keyword “TWIN” which as far as I understand it is all we need to do for twinned data then refmac fails to run with a "array size in mtz_refl_read_int” error. Please see the log file attached. Can anyone please help with this as it is obviously important that we run both with and without twinned refinement to make sure that we are refining our structure appropriately. Thanks and best wishes, *That is a REFMAC error I believe.. Garib? * Error==> array size in mtz_refl_read_int <B><FONT COLOR="#FF0000"><!--SUMMARY_BEGIN--> Refmac: Problem with array sizes On Mon, 1 Oct 2018 at 11:56, Kyle Stevenson - UKRI STFC < kyle.steven...@stfc.ac.uk> wrote: > Hello, > > > > I’m sure mostly everyone is also on the regular list, but just > in case :- > we’ve had a report of an issue using Refmac with the twinning option > switched on. > > I’m not sure if this is a problem on our end, or something in Refmac, > > > > Cheers, > > Kyle. > > > > > > *From:* owner-c...@dlmail2.dl.ac.uk [mailto:owner-c...@dlmail2.dl.ac.uk] *On > Behalf Of *Glyn Hemsworth > *Sent:* 01 October 2018 11:40 > *To:* CCP4 > *Subject:* [ccp4]: CCP4i2 Refmac TWIN failing > > > > Hello, > > > > I’m not sure whether this is a refmac issue or a ccp4i2 issue but we have > recently solved the structure of a protein which appears to be twinned in > the space P43 with 10 molecules in the asymmetric unit.
