Provide equivalent of COLETTE DISPLAY H & DISPLAY V diagnostic

[Nick Draper]

Need a Gui or tab on SANS system as suggestions below. H and V plots use SumRowColumn, T – time plots use SumSpectra as per python examples below.

Mockup at ​http://svn.mantidproject.org/mantid/trunk/Documents/Design/Mockups/SANS/Diagnostics.bmml

Detail provided by Richard Heenan

Text Boxes for:

Run number & period      [ assume directory etc as per main SANS gui ]

----------------------

6 QUICK BUTTONS for:                      [we use these 6 a great deal, so don’t want to have to keep reselecting options]  

D_H      (front detector)        [or main for LOQ ]
D_V               “
D_T               “

D_H      (rear detector)           [ or HAB for LOQ]
D_V               “
D_T               “

Note  D_T here needs to apply the current detector pixel mask and beam stop  [it doesn’t in COLETTE but would be useful here]
D_H or D_V need to apply the current detector time channel mask.

---------------------------

DETAILED LOOK SECTION

Drop down for: front/rear (SANS2d)  OR  main/HAB (LOQ)

3 Buttons each with a text list input box for:

D_H     “range”
D_V     “range”
D_T      “region”


Where “range” is a list like    
Add a list:
2010+2012 (one workspace of the sum of these two)
Add a range of files:
2010-2012 (one workspace of the sum of these three)
2010-2012:2 (in steps of 2)

Load a list of files:
2010,2012 (2 Workspaces)
Load a range of files:
2010:2012 (3 workspaces)
2010:2012:2 (steps of 2)

Of course you can mix them up, so
60-61,62+63,64-65 would work


“Region” is any valid part of a detector such as H60, H60-H68, V10-V12+,H16-H29  as already used in the mask files (i.e. we already have a parser that turns these into a list of spectra) to produce a single workspace; and if possible a list like “V60:V64” to produce 5 workspaces. 

D_H or D_V should ideally optionally apply the current time channel mask for that detector. Add a drop down next to “range” text boxes.

D_T should  ideally optionally apply the current detector pixel mask and beam stop, “not apply” should be the default. Add a drop down next to “region” text box.

Check that row or column numbers are valid:  0 to 191 for SANS2d, 0 to 127 for LOQ.

Name output workspaces appropriately.

(In [8286]) mockup added re #2155

[Nick Draper]

(In [8289]) update to mockup re#2155

[Sofia Antony]

(In [9183]) re-#2155 created a new class UserStringParser to parse the user given string.This class gives a method parse which takes a string as input and returns a vector of vectors of numbers by splitting the string to different tokens using separators +,-,:

[Sofia Antony]

(In [9186]) re#2155- fix for build failures

[Sofia Antony]

(In [9187]) re#2155- fix for test failures

[Sofia Antony]

(In [9235]) re#2155- added two methods to return the min and max detector ids of the rectangular detector

[Sofia Antony]

(In [9237]) re#2155- new tab Diagnostics is added to SANS GUI which is an equivalent of COLETTE DISPLAY H & DISPLAY V.

[Sofia Antony]

(In [9238]) re#2155- fix for build failure.Forgot to check in this file.

[Sofia Antony]

(In [9240]) re#2155- fix for build failure.

[Sofia Antony]

(In [9259]) re#2155- some improvements to SANS diagnostics tab.Now the first tab is changed back to Run Numbers.

[Sofia Antony]

(In [9260]) re#2155 - Renamed some of the functions,added error messages.

[Sofia Antony]

(In [9261]) re#2155 - Forgot to submit this file in the previous check in.

[Sofia Antony]

(In [9265]) re#2155 - fix for build failure.I'm commenting some of the tests temporarily.

[Sofia Antony]

(In [9268]) re#2155 - fix for unit test failure.Enabled the commented tests.

[Sofia Antony]

SANSDiagnostics tab will not work if we load a nexusprocessed file. This is becouse LoadNexusProcessed algorithm is not populating the entire spectrum detectormap when the first spectrum is loaded and I'll be creating new ticket for this.

[Sofia Antony]

Loading is not working with diagnostics tab.I'm looking into this.

[Sofia Antony]

(In [9495]) re#2155 - Fix for SANSDiagnostics loading.Changed the script for load algorithm and now it loads data. Also changed LoadNexusProcessed algorithm to populate the entire spectrum-detector map when we load few spectra using the SpectrumMin and SpectrumMax options.

[Sofia Antony]

(In [9498]) re#2155 - Fix for load nexus processed spectrum detector map population

[Steve Williams]

The tab works but could be improved slight with these small alterations:

• Change the QLabel towards the top of the tab to remove the captial R at the start of range string and the format string that isn't supported "60-66:2". It could start

Example ranges: 60-65 60:66

• The run filename is remembered by the run widget which is annoying as you have to clear it to select the file you want. Even if you want to use that same filename it doesn't make it easier. I suggest clearing the filename on start up.
