MergeCalFiles dialog.

Properties

Name Direction Type Default Description
UpdateFile Input string Mandatory The cal file containing the updates to merge into another file. Allowed values: [‘cal’]
MasterFile Input string Mandatory The master file to be altered, the file must be sorted by UDET. Allowed values: [‘cal’]
OutputFile Input string Mandatory The file to contain the results. Allowed values: [‘cal’]
MergeOffsets Input boolean False If True, the offsets from file1 will be merged to the master file. Default: False
MergeSelections Input boolean False If True, the selections from file1 will be merged to the master file. Default: False
MergeGroups Input boolean False If True, the Groups from file1 will be merged to the master file. Default: False

Description

Combines the data contained in two cal files, based on the selections offsets, selections and groups can be merged. The matching rows are determined by UDET. Any unmatched records are added at the end of the file.

Usage

Example - Merging and appending files

import os

#find a suitable directory to save the files
file_dir = config["defaultsave.directory"]
if not os.path.isdir(file_dir):
    #use the users home directory if default save is not set
    file_dir = os.path.expanduser('~')

def writeCalFile(file_name,num_dets,inc_group=True,inc_offset=True,inc_selected=True):
    file_path = os.path.join(file_dir,file_name+".cal")
    #write the cal file out
    with open(file_path, "w") as file:
        for line_no in range(num_dets):
            file.write("%i\t%i\t%f\t%i\t%i\n" %
            (line_no,
             line_no + 100,
             (line_no / 1000.0) if inc_offset else 0.0,
             (line_no % 2) if inc_selected else 0,
             (line_no % 3) if inc_group else 1) )
    return file_path

calFile_master = writeCalFile("masterCal",6)
calFile_updates = writeCalFile("updateCal",3,
    inc_group=False, inc_offset=False, inc_selected=False)
output_file = os.path.join(file_dir,"output.cal")

MergeCalFiles(
    UpdateFile = calFile_updates,
    MasterFile = calFile_master,
    OutputFile = output_file,
    MergeOffsets = True,
    MergeSelections = True,
    MergeGroups = True)

#Load and print the resulting file
print("The result file has been updated with 0 for group, select and offset\nwhere the detector id's match")
with open(output_file, "r") as file:
    print(file.read().rstrip())

#cleanup
os.remove(calFile_master)
os.remove(calFile_updates)
os.remove(output_file)

Output:

The result file has been updated with 0 for group, select and offset
where the detector id's match
        0             100       0.0000000        0        1
