Batch Processor Invalid Frame Range

Post by lschutz » Thu Jun 28, 2018 1:18 pm

Hello,

For a study, I am recording multiple trials in a single .tak. For data cleaning and csv export, I then trim the .tak file maintaining the original frame numbers to combine with .tak start time and generate timestamps. I am having trouble using the batch exporter with .tak files that are in this format.

I have attached a screenshot of the error message and the batch processing script I am using is copied below. For now, I can avoid the error by manually entering the start frame and end frame in the script as I have commented out, but with this fix I am only able to process one .tak at a time, avoiding the main benefit of using the batch processing script. Is there a way to code into the script an automatic determination of start and end frame?
