[Mathieu Doucet]

(In [5297]) Updated HFIR/SANS reduction script. Re #1334

[Mathieu Doucet]

(In [5311]) Put the validation tests in a separate script. Re #1334.

[Mathieu Doucet]

(In [5319]) Minor cleanup. Re #1334.

[Mathieu Doucet]

(In [5969]) Make the normalization the first step in the reduction so that the timer/monitor doesn't get overwritten by other corrections. Re #1334

[Mathieu Doucet]

This ticket is becoming too general. I'm closing it and all further improvements will have their own ticket.

[Janik Zikovsky]

I go to the Interfaces menu -> HFIR/SANS reduction and I get this error

AttributeError: "'QFile' object has no attribute 'rfind'" in file 'posixpath.py' at line 119

and nothing opens... This is on Ubuntu 10.10, debug compiled version of MantidPlot.

[Mathieu Doucet]

(In [7160]) Make reduction_application code compatible with python 2.4. Re #1334

[Janik Zikovsky]

There may be some local issue - (did not use installer since I'm on ubuntu) so i'll let someone else test this.

[Peter Peterson]

"Interfaces->HFIR_reduction" still generates the error message:

AttributeError: "'QFile' object has no attribute 'rfind'" in file 'posixpath.py' at line 119

on ubuntu with

>>> print sys.version
2.6.6 (r266:84292, Sep 15 2010, 16:41:53) 
[GCC 4.4.5]

[Mathieu Doucet]

Which version of PyQt?

[Peter Peterson]

According to the package manager my version of python-qt4-dev is 4.7.4-0ubuntu1

[Peter Peterson]

The continuation of this saga is going on #1847.

[Stuart Campbell]

Works ok on ubuntu 10.04 which has python-qt4-dev 4.7.2
