CR3000 table data merge

Terenzio Jan 14, 2016 08:34 AM

Hi all

I was wondering if with loggernet there's the possibility of merging high frequency data (10 Hz) collected in one file (all files of 30 min lenght ) with data present in another files. Both files (and data acquisition) are synchronized but for the data processing the 2 two files have to be merged in one. Does anyone know how to do it?

You can do quite a bit of data file manipulation with SplitW(part of Loggernet), however you wouldn't be able to interlace data from two source files with it.

Practically all programming languages can manipulate text files. Windows/DOS batch files can do quite a bit. Python is popular and can do anything you want to a data file once you learn to use it.

Excel is not striaghtforward, but could be easier than writing command line code.

Looking into it more, it is probably possible in Split. Use "Add Data File" from the Edit menu. 

In the help, read the topic:

"Synchronizing Two or More Data Files Synchronizing Two or More Data Files"

10Hz data is the fastest data that Split can sync. The data from the CR3000 is 'Table Based Data'.

If you are going to use card convesion utility, in conversion option you will find "append to Last file". It worked perfectly with me
