Modifies an ISIS detector dot data file, so that the detector positions are as in the given workspace
Name | Direction | Type | Default | Description |
---|---|---|---|---|
InputWorkspace | Input | Workspace | Mandatory | Workspace with detectors in the positions to be put into the detector dot dat file |
InputFilename | Input | string | Mandatory | Path to a detector dot dat file. Must be of type .dat or .txt. Allowed extensions: [‘.dat’, ‘.txt’] |
OutputFilename | Input | string | Mandatory | Path to the modified detector dot dat file. Must be of type .dat or .txt. Allowed extensions: [‘.dat’, ‘.txt’] |
Modifies an ISIS detector dot data file, so that the detector positions are as in the given workspace. This algorithm can be used to transfer a calibration done via the ApplyCalibration v1 algorithm to an ISIS detector dot dat file by selecting a workspace that has been modified by ApplyCalibration.
A typical ISIS dot data file has a format like this:

Each row corresponds to a detector whose type is indicated in the
code
column. The algorithm will only modify values in columns l2
,
theta
and phi
and only if the value in the code
column is 3,
which indicates a PSD gas tube. For more details about the detector dot
data file see
LoadDetectorInfo#File_format.
Example - Modify a simple dot dat file
import os
result = Load("MUSR00015189")
group = result[0]
ws_1 = group[0]
ws_2 = group[1]
newFile = os.path.join(os.path.expanduser("~"), "detector_1_M.dat")
# Run the Algorithm
ModifyDetectorDotDatFile(ws_1, "detector_1.dat", newFile)
# Check the output file
print("File Exists: {}".format(os.path.exists(newFile)))
f = open( newFile, 'r' )
file = f.read().split('\n')
f.close()
for line in file[0:4]:
# print the line truncating before system dependent line break can take effect
# also stripping off any trailing spaces
print(line[0:89].rstrip())
Output:
File Exists: True
