 * 10324 - against YFP
 * 11586 - random sorting
 * 13087 - against CFP

7/11/07

 * cleaning period = 15.9
 * same as 5/29/07, otherwise

7/11/07b
fluid 5.5 pushup: 19.64 pushdown: 21.80
 * cleaning period = 14.8
 * Focus: 1375, 1984, 2102, 3648, 4068, 5600, 6022, 7502, 8008, 9100, 9718, 9927, 11062, 13036, 13638, 13662, 15358
 * 1436 - Started sorting againstYFP
 * 9927 - turned off sorting
 * 13708 - started sorting againstCFP

9/11/07

 * 40 to 60% zig-zag experiment.
 * If possible do pulse selection as well
 * cleaning period = 15.9
 * same as 5/29/07, otherwise
 * Focus and flipped the 2x magnification at #63 (I was seeing cells outside the sorting chamber).

12/2/07

 * 1418 - focused
 * 3832 - focused for BF images.

12/18/07

 * 64 - switched to sorting against CFP, since it looked like they might be growing faster (though too early to tell, really)
 * 94 - turned off directional sorting
 * 748 - focused
 * 752 - directional sorting against CFP
 * 1321 - focused
 * 3228 - got through >3000 w/o a memory leak crash, as a point of reference. (though PF at 1.2MB)
 * Also, note that this chip has been in constant use since 12/2 (16days), although i did have to reload the pump valves at day 14, b/c one had dried out. I think its reasonable that we could keep a culture going in here for at least 16 days (though in this run, i swapped n new cells a couple times, though one set was in there for 10 days) - and probably for much longer if you periodically reloaded the pump valves.

12/20/07

 * 462 - directional sorting against CFP

12/22/07

 * Using C/Y (3k3)
 * Mixed CFP (OD = 0.12) and YFP (OD=0.10), so they would be present 50/50 from cultures that had been inoculated from a colony ~6 hours earlier.
 * 112 - turned on sorting (non-directional)
 * 817 focused

12/23/07

 * 200 - turned on sorting (non-directional)
 * 230 - focused
 * 494 - focused and turned on directed sorting against CFP, also turned on the "flipping" from 0.4-0.6

12/24/07

 * 20.5 cleaning period, which should be a doubling time of 0.9hr.
 * 368 - set to against YFP / focused
 * 492 - actually turned on the flipping 0.4-0.6 switch. So should flip to against CFP very soon (if not immediately).
 * 1224 - focused
 * 1700-focused

12/25/07

 * 19.3 cleaning period, which should be a 0.85 hr doubling time.
 * 634 focused
 * Good example of non-directional w/ sorting, however the counts for the CFP were consistently 4-5 cell high, so I changed the std_mult variable to be 5 for the 12/26 run.

12/26/07

 * 19.3 cleaning period, which should be a 0.85 hr doubling time.
 * 166 - focused
 * 564- changed to sorting against YFP (was sorting against CFP for a fair number of sorts before this)

12/28/07

 * 715 - turned on non-directional sorting
 * 720 - turned on directional sorting (in this case that just means selecting for GFP cells)
 * 1630 - focused
 * 3536 - focused & turned off directional sorting
 * 4067 - focused

1/15/08

 * push down, push up = 20psi
 * fluid = 5.6 psi


 * 1 - started with cleaning only
 * 155 - focused
 * 162 - turned on sorting (directional) in favor of GFP
 * 462 - focused (~16 total cells, 4 of which were glowing)
 * 524 - switched sorting to non-directional (there was a bug so didn't really)
 * 708 - fixed the bug in the sorting, in the process I did two cleaning events in quick succession, but I restarted at the same cleaning event it was at previously.
 * 1560 - changed sorting to directional in favor of GFP
 * 1950 - focused
 * 2550 - focused
 * 4136 - focused
 * 4716 - focused
 * 5318 - focused
