ShiftLogTime dialog.
Table of Contents
Shifts the indexes of the specified log. This will make the log shorter by the specified shift.
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InputWorkspace | Input | MatrixWorkspace | Mandatory | A workspace with units of TOF |
| OutputWorkspace | Output | MatrixWorkspace | Mandatory | The name to use for the output workspace |
| LogName | Input | string | Name of the log to add the offset to | |
| IndexShift | Input | number | 0 | Number of (integer) values to move the log values. Required. |
The algorithm is similar to ChangeLogTime, but instead of a defined time shift of the logs, one gets a shift in the indexes of the specified logs. This will make the log shorter by the specified shift.

import numpy as np
#Load a workspace
w = Load('CNCS_7860')
#get the log times for a particular variable
original = w.getRun()['Speed5'].times
#Change the log times
w = ShiftLogTime(w, LogName='Speed5', IndexShift='2')
#get the log times for a particular variable, after change
modified = w.getRun()['Speed5'].times
#print times
print("OriginalTimes: {}".format(np.datetime_as_string(original, timezone='UTC')))
print("ModifiedTimes: {}".format(np.datetime_as_string(modified, timezone='UTC')))
Output:
OriginalTimes: ['2010-03-25T16:09:27.780000000Z' '2010-03-25T16:10:01.560998229Z'
'2010-03-25T16:10:31.514001159Z' '2010-03-25T16:11:25.498002319Z']
ModifiedTimes: ['2010-03-25T16:10:31.514001159Z' '2010-03-25T16:11:25.498002319Z']
