You can run Field Assembler from the command line or from a batch file and have it automatically assemble sequences of images and automatically exit. To run using the command line, you must give FieldAssembler.exe three parameters:
FieldAssembler EvenInputSequence.# OddInputSequence.# OutputSequence.#
Specify the files for the image sequence you wish to convert. You can use the # symbol to indicate where the frame numbers are, or the number for the first file. If you use the # symbol, the first number will be zero (0). If the numeric increments are 10 or less, this will automatically find all images in the sequence. This parameter should specify the full path to the files.
Specify the name of the output sequence. You can use the # symbol, or the number of the first frame, just as you would on the input sequence. Increment will always be 1.
Running from the command line in this manner will bring up the Field Assembler Window, assemble the images, and close the Field Assembler Window.
If you wish to run from a batch file, and not continue until the assembly is complete, you can write it using the Start /WAIT command:
Start /wait FieldAssembler EvenInputSequence.# OddInputSequence.# OutputSequence.#
