Description¶
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.
Usage¶
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
