SumNeighbours crashes on EnginX

[Owen Arnold]

This is apparently caused when the sum regions exceed about 1% of the total data.

User has provided this script, which is supposed to replicate the issue.

import sys
import os
sys.path.append(os.environ['MANTIDPATH'])
from mantid.simpleapi import * #Loads the Mantid algorithms
 
#Runnumber=str(raw_input('Enter the 8 digit run number: ')) #Will load a .RAW file without an extension
Runnumber='00185905'
#Pixels=str(raw_input('Enter the number of pixels to sum over: '))
Pixels=24
LoadedWorkspaceName= 'ENGINX' + Runnumber + '.raw'
ConvertedWorkspaceName=Runnumber + '-d2'
SummedWorkspaceName='Sum' + Runnumber
Load(Filename=LoadedWorkspaceName,OutputWorkspace=LoadedWorkspaceName, SpectrumMax='2400' )
ConvertUnits(InputWorkspace=LoadedWorkspaceName,OutputWorkspace=ConvertedWorkspaceName,Target='dSpacing',AlignBins='1')
SumNeighbours(InputWorkspace=ConvertedWorkspaceName,OutputWorkspace=SummedWorkspaceName,SumX=Pixels,SumY='1')

Using the latest build of master the script completes successfully without a crash for me.

It works for me after I copied the raw file across. It alspo worked when I also copied across the accompanying files of the raw file, so showing no problem processing those files either.

The user did not specify, which type of computer the problem occurred on. It therefore needs testing on all supported systems. I tested on Windows7. I return to testing pool for it to be tested on other systems.

[Harry Jeffery]

I tested on Ubuntu 14.04

[Owen Arnold]

Agreed. Tested on OSX. Cant get it to crash.
