Description¶
Sort a peaks workspace by a single column. Sorting of that PeaksWorkspace by that column can either happen in an ascending or descending fashion. The algorithm can either be used to generate a new OutputWorkspace, which is sorted as requested, or to perform an in-place sort of the InputWorkspace.
Usage¶
Example - sort a peaks workspace by column name:
peaks_ws = LoadIsawPeaks(Filename='TOPAZ_1204.peaks')
#sort the table by column k
peaks_ws = SortPeaksWorkspace(peaks_ws, ColumnNameToSortBy='k')
print("Column k in ascending order: " + str(peaks_ws.column('k')))
#the algorithm can also sort in descending order
peaks_ws = SortPeaksWorkspace(peaks_ws, ColumnNameToSortBy='k', SortAscending=False)
print("Column k in descending order: " + str(peaks_ws.column('k')))
Output:
Column k in ascending order: [-3.0, -2.0, -2.0, -2.0, -2.0, -2.0, -2.0, -1.0, -1.0, -1.0, -1.0, -1.0, -1.0, -1.0, -1.0, -0.0, -0.0, -0.0, 0.0, -0.0, -0.0, 0.0, -0.0, 0.0, 0.0, 0.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 2.0, 4.0, 5.0, 5.0]
Column k in descending order: [5.0, 5.0, 4.0, 2.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, -0.0, -0.0, -0.0, 0.0, -0.0, -0.0, 0.0, -0.0, 0.0, 0.0, 0.0, -1.0, -1.0, -1.0, -1.0, -1.0, -1.0, -1.0, -1.0, -2.0, -2.0, -2.0, -2.0, -2.0, -2.0, -3.0]
