From 6dab661ded9c2c7b555ccb05913a55db0f89bef6 Mon Sep 17 00:00:00 2001 From: Wenduo Zhou Date: Mon, 9 Mar 2015 07:22:14 -0400 Subject: [PATCH] Refs #11282. Fixed some issues related to reduce HFIR data. 1. LoadSpiceAscii has date time format with default to SPICE's current standard 2. ConvertCWPDMDToSpectra is explained in the sumary; 3. Binning parameters can accept bin size only in ConvertCWPDMDToSpectra. Xmin and Xmax will be searched automatically. - modified: ../Mantid/Framework/DataHandling/src/LoadSpiceAscii.cpp - modified: ../Mantid/Framework/MDAlgorithms/inc/MantidMDAlgorithms/ConvertCWPDMDToSpectra.h - modified: ../Mantid/Framework/MDAlgorithms/src/ConvertCWPDMDToSpectra.cpp - modified: ../Mantid/Framework/MDAlgorithms/test/ConvertCWPDMDToSpectraTest.h --- .../DataHandling/src/LoadSpiceAscii.cpp | 18 +- .../ConvertCWPDMDToSpectra.h | 14 +- .../src/ConvertCWPDMDToSpectra.cpp | 159 +++++++++++++++++- .../test/ConvertCWPDMDToSpectraTest.h | 49 +++++- 4 files changed, 224 insertions(+), 16 deletions(-) diff --git a/Code/Mantid/Framework/DataHandling/src/LoadSpiceAscii.cpp b/Code/Mantid/Framework/DataHandling/src/LoadSpiceAscii.cpp index 55c0d34ca3a5..879dbb975bc0 100644 --- a/Code/Mantid/Framework/DataHandling/src/LoadSpiceAscii.cpp +++ b/Code/Mantid/Framework/DataHandling/src/LoadSpiceAscii.cpp @@ -129,8 +129,16 @@ void LoadSpiceAscii::init() { "Otherwise, any log name is not listed will be treated as " "string property."); - declareProperty(new ArrayProperty("DateAndTimeLog"), - "Name and format for date and time"); + // date: MM/DD/YYYY,time: HH:MM:SS AM is the standard SPICE date time log name + // and format + std::vector defaultlogformat(4); + defaultlogformat[0] = "date"; + defaultlogformat[1] = "MM/DD/YYYY"; + defaultlogformat[2] = "time"; + defaultlogformat[3] = "HH:MM:SS AM"; + declareProperty( + new ArrayProperty("DateAndTimeLog", defaultlogformat), + "Name and format for date and time"); // Output declareProperty(new WorkspaceProperty("OutputWorkspace", "", @@ -461,8 +469,10 @@ void LoadSpiceAscii::setupRunStartTime( runinfows->run().hasProperty(timelogname))) { std::stringstream errss; errss << "Unable to locate user specified date and time sample logs " - << datelogname << " and " << timelogname << "."; - throw std::runtime_error(errss.str()); + << datelogname << " and " << timelogname << "." + << "run_start will not be set up."; + g_log.error(errss.str()); + return; } const std::string &rawdatestring = diff --git a/Code/Mantid/Framework/MDAlgorithms/inc/MantidMDAlgorithms/ConvertCWPDMDToSpectra.h b/Code/Mantid/Framework/MDAlgorithms/inc/MantidMDAlgorithms/ConvertCWPDMDToSpectra.h index 453b48e60951..b2176621470c 100644 --- a/Code/Mantid/Framework/MDAlgorithms/inc/MantidMDAlgorithms/ConvertCWPDMDToSpectra.h +++ b/Code/Mantid/Framework/MDAlgorithms/inc/MantidMDAlgorithms/ConvertCWPDMDToSpectra.h @@ -108,8 +108,12 @@ class DLLExport ConvertCWPDMDToSpectra : public API::Algorithm { /// Summary of algorithms purpose virtual const std::string summary() const { - return "Binning the constant wavelength powder diffracton data stored in " - "MDWorkspaces to single spectrum."; + return "Convert constant wavelength (CW) powder diffraction (PD) data in " + "MDEventWorksapces " + " to a single-spectrum MatrixWorkspace, i.e., binning the " + "diffraction data " + " to single spectrum according to neutron's scattering angle, " + "d-spacing or Q.
