What is the correct way to read a .exr file and convert it to .flo?

edit

To convert a .exr file to .flo, you can use a software called "exr2flo". This tool can be downloaded and installed from the internet. Once installed, follow these steps to convert the file:

1. Open the command prompt or terminal.
2. Navigate to the location of the exr2flo tool.
3. Type the command "exr2flo input.exr output.flo" (replace "input.exr" with the name of your input file and "output.flo" with the desired name of the output file).
4. Press enter and wait for the conversion to complete. The converted .flo file should now be in the same directory as the input file.

Note: The .flo file format is designed for optical flow data, so make sure that the .exr file you are trying to convert contains such data.
