Pumps randomly diluting out the culture

Hi @fkuzminov,

We’re still thinking through the root cause of the problem, but for now, I think using your suggestion of using the median value instead of the mean could help.

In custom_script.py:


        # Determine whether turbidostat dilutions are needed
        if len(data) > 7:
            # Take median to avoid outlier
            od_values_from_file = []
            for n in range(1,7):
                od_values_from_file.append(data[len(data)-n][1])
            average_OD = float(np.median(od_values_from_file))

This should replace the following around line 103:


        if len(data) > 7:
            for n in range(1,6):
                average_OD = average_OD + (data[len(data)-n][1]/5)
