Stitch1DMany Bug Report

[Owen Arnold]

Attached are two files 1) a pdf and 2) ipython notebook used to create the pdf.  The scripts used are the ones I've forwarded to you previously.  

I've observed some issues with Stitch1DMany. 

1) I only get one scale factor from the output. 
2) When comparing with the genie stitch,  Stitch1DMany mis-calculates or mis-applies a scale factor which results in and offset in intensity for data which should be similar.   The results from Stitch1DMany are on page 5 of the PDF and the genie results are shown on page 6. 

On a side note it would be nice if the function to identify the name and number of returned values from a python function was exposed to us.  Currently I've copied in this set of function from else where which may not be the best approach.

I emailed the following python script to Tim to show how information about the inputs of an algorithm could be dynamically fetched:

import mantid.api

alg =AlgorithmManager.createUnmanaged("Stitch1D")
alg.initialize()
properties = alg.getProperties()
for prop in properties:
         print prop.name, " Input" if prop.direction==0 else" Output"

Tester

1) Stitch1DMany has been adapted to return all calculated scale factors. Unit tests have been updated to reflect this.

2) Tim has been contacted about how to get algorithm property information

3) ticket #9549 has been opened to determine any possible issues with scale factors in Stitch1D
