Mostly as an excuse to learn some javascript, I have started piecing together a simple interface for running FBA models. http://140.221.84.246/microbes_model_runner/fba_model_runner.html The interface allows you to create a table of runFBA parameters, with different media conditions for each column and model formulations for each row. Calls to runfba are automatically generated, and the table is filled in with growth results as the runfba jobs are completed. See the attached screenshot for an example. Since this minimal interface may already be useful for some of you, I thought I'd send it around now for testing and to see what everyone thinks. I can only take partial credit for what you see - the nicer looking bits were mostly stolen from Matt and Bill's model builder, and Paramvir came up with the original idea :) . -michael
