Question How to bulk process MagArrow magdata files?

If you have many .magdata files to convert, it is more convenient to use the command-based MagArrowConverter, instead of the Windows-based Survey Manager. The MagArrowConverter installation file can be downloaded from the same download section as the Survey Manager: https://www.geometrics.com/product/magarrow/ .

To use the MagArrowConverter:

• Run “MagArrowConverterInstaller.exe” to install the converter. It is recommended NOT to install the converter on the default C:\Program Files\ directory since some computer may not allow users to create files in this directory.
• Open Windows Command (“cmd”) and enter the directory where the converter is installed.
• Type MagArrowConverter and press Enter key. A short instruction of how to use the converter will be printed out.

• If you run it from a different directory, type the full path, e.g. "C:\ Geometrics\MagArrowConverter\MagArrowConverter" (assuming the program is installed in C:\ Geometrics\MagArrowConverter\ directory).
• Note that to change the installation directory, you will have to un-installed the program first and then re-install and set up the directory.
• A typical example command: …\MagArrowConverter type=MA1 format=csv1 input=”C:\test\test.magdata” output=”C:\test\test.csv” decimation=10
• A new csv file with sample rate of 10Hz will be created in C:\test directory from test.magdata file.
• After you become familiar with MagArrowConverter command, you can write a simple Batch Script to bulk process MagArrow .magdata files.

An example batch code which searches for .magdata files in "C:\MagArrowData" folder and converts all files to .csv files at 10Hz is attached below.
