Key Features#
This is a patch release to correct some significant issues since the last full release. There are updates to fix a threading issue causing problems with the reduction of certain large instruments, a problem when adding SANS event files, improvements to MPI processing, corrections to some instrument geometries and some improvements to EQSANS reduction.
Changes in this version#

Problem |
Impact |
Solution |
|---|---|---|---|
#8398 (Trac 7553) |
Improvements to NOMAD autoreduction with MPI |
Problems with the MPI reduction prevented usage. |
Rebin into histograms rather than maintain event data. ensure correct chunking of the can and vanadium files |
#8445 (Trac 7600) |
Defect on SANS2D adding data |
Event data files can be corupted when adding files togeter using the SANS interface. |
Correctly take into account any monitors when merging event files |
#8522 (Trac 7677) |
Reduction for several inelastic instruments hangs part way through reduction |
Instruments such as TOSCA, MERLIN and LET cannot use Mantid v2.6 to reduce their data. |
Use lazy loading for Workspace details and improve locking approaches |
#8530 (Trac 7685) |
MPI runs can fail in SNSPowderReduction |
In sertain situations the reduction could fail part way through |
Added a check that the data is indeed still in events before running CompressEvents. |
#8544 (Trac 7699) |
EQSANS: reducing existing workspace fails |
Reduction has to use the file every time even if it is already loaded |
This used to work in previous versions, correct the area of the scripts that does not support this |
#8546 (Trac 7701) |
EQSANS: make sure transmission workspaces are created |
||
#8550 (Trac 7705) |
Load not working with Dave grouped file with different extension |
GRP files with a .dat extension are not shown |
Add *.dat onto the list of extensions |
#8563 (Trac 7718) |
“Do Not Rebin” option causes error with TOSCA |
||
#8565 (Trac 7720) |
Problem with boolean properties and GUI |
Boolean properties that have a default of true do not get set |
Revert change that caused the issue |
#8589 (Trac 7744) |
Default values are not being shown when running algorithm dialog form script interpreter |
Some algorithms might not work in the way that users are used to |
Fix the problem with default value logic |
#8611 (Trac 7766) |
Mistake in latest powgen geometry |
POWGEN files from current run cycle |
Updated instrument geometry |
