Series Labeler --headless

I would like to be able to label a time series image stack. Series Labeler works well in my macro when I run the macro from the GUI. It throws exceptions when I run the same macro in headless mode.

run(“Bat Cochlea Volume (19K)”);
run(“Series Labeler”, “stack_type=[time series or movie] label_format=[Custom Format] custom_suffix=minute custom_format= label_unit=[Custom Suffix] decimal_places=0 startup=0.000000000 interval=30.000000000 every_n-th=1 first=0 last=114 location_presets=[Upper Left] x_=0 y_=0”);

Is there a work around or another plugin that can label each image of a time series with its time label?

thanks for any help…
