MergeFiles

Opens and merges the specified files, returns the reference to the merged file.

Syntax

MergeFiles(filename_list, gap)

Parameters

Parameter	Type	Description
filename_list	string	The list of files to be merged. File names should be separated by commas
gap	number	Gap between the files (in seconds). See Note below.

Return

Returns the reference to the merged file.

Note

In the merge process, the data (for the same variable) from the second file is appended to the data from the first file. Before appending, the timestamps of the variables in the second file are shifted by the value equal to duration_of_the_first_file + gap.

Since the function uses commas as separators between file names, it is assumed that each file name does not contain commas.

Examples

Python

import nex
import json
dataDir = "C:\\Data\\"
files = []
files.append(dataDir + "file1.nex5")
files.append(dataDir + "file2.nex5")
doc = nex.MergeFiles(json.dumps(files), 1.)

NexScript

dataDir = "C:\Data\"
file1 = dataDir + "file1.nex5"
file2 = dataDir + "file2.nex5"
mergeList = file1 + "," + file2
doc = MergeFiles(mergeList, 1.)
