SANS reductions with different phi masking

[Steve Williams]

Sectors are masked around the beam center to analyse non-circularly symmetric scattering patterns better. It would be useful if the GUI and user file could automatically set up reductions for multiple pairs of phi ranges. The syntax requires some thought.

The user will be able to write pairs of numbers into a box with a separator between the pairs. Each pair will create one reduced workspace.

There will be documentation here This will be all documented and work as explained in documents linked from here http://www.mantidproject.org/Using_the_SANS_GUI_Analysis_Details

"New" tickets moved at the code freeze of iteration 29

[Steve Williams]

Personally, I really don’t like the idea of ‘to’.

If not brackets, is there anything else that can be used to separate pairs? a,b ; c,d ; e,f ?

Bulk move of tickets to iteration 31 at the iteration 30 code freeze

[Anders Markvardsen]

An python ISIS SANS command 'PhiRanges' was added with the description:

def PhiRanges(phis, plot=True):

"""

Given a list of phi ranges [a, b, c, d] it reduces in the phi ranges a-b and c-d

Currently PhiRanges is not used anywhere in Mantid.

I have tested this command with:

from ISISCommandInterface import *

SANS2D() MaskFile('MASKSANS2D_094i_RKH.txt') Gravity(False) Set1D() AssignSample('2500.nxs') out = PhiRanges([1, 10, 20, 30]) print help(out) print len(out)

and I am concerned it is not yet coded to do what requested

[Anders Markvardsen]

Agreed in meeting yesterday that notation "a, b, c, d" meaning do independent reductions a-b and c-d is OK.

Also the output workspaces names must reflect what phi range used. Suggested to append phiNUMBER_NUMBER

[Anders Markvardsen]

The output of this ticket is the command PhiRanges. Separate ticket for executing this from GUI is #4102.

Remember to display warning if odd number of phi input numbers are provided by user

Don't add phi file extension when 2D reduction. Re #3015

Changeset: d68a8e022409fd3c918eddd111523c1f6c4b6f7c

[Anders Markvardsen]

This one has been fixed and it has been verified by Richard Heenan during last weeks scientist testing period that it works. Apologizes for forgetting to close this ticket earlier. If someone insist on testing this, in addition to Richard, then load data into ISIS SANS GUI, e.g. use the test data in systemtest SANS2DMultiPeriodAddFiles and also the mask file this systemtest is using

Closed at iteration end
