Why have some workflows finished but not others?

To understand this I need to explain where all the images come from. A small part of each sample of Tuberculosis is injected into each well of a 96 well plate; the plate is quite small – a bit bigger than an iPhone. Every well has a specific amount of an antibiotic dried onto the bottom of the plate, except two wells which have no antibiotic at all. There are fourteen different antibiotics on one plate; one with only 4 different dosages, four with 5, seven with 6 and two with 8.

 

Each 96 well plate is also photographed after 7, 10, 14 and 21 days. Each photo is automatically cut up into strips, hence there are seven different strips with 6 wells from each image, but only one strip with 4 wells. Because of the way the Zooniverse website works, this means there are four different workflows which differ by the number of wells. But, each workflow also contains photos taken at four different days! (See, it is getting complicated). Basically, the 4 wells and 8 wells workflows have been completed – thank you – they took the least amount of time because they didn’t have as many images in them. All the day 14 photos are done and we are about 60% of the way through the day 21 photos. Once these are also completed we can analyse and compare both datasets and then come back to the days 7 and 10 images later.
