00:00:00.0 --> 00:00:04.0
Hi everyone, this is rprentki with another tutorial video for EyeWire.

2
00:00:04.0 --> 00:00:09.0
This is going to be the sixth practice cube after the six tutorial cubes that you did.

3
00:00:09.0 --> 00:00:12.5
So once again, you're not going to get any feedback while you're working, 

4
00:00:12.5 --> 00:00:14.5
you will get feedback at the end 

5
00:00:14.5 --> 00:00:17.0
and you'll start getting some points for these.

6
00:00:17.0 --> 00:00:19.0
Let's get started.

7
00:00:30.0 --> 00:00:33.0
So far nothing to add, but hopefully we'll get something in a bit.

8
00:00:37.0 --> 00:00:39.0
Okay, a little piece there.

9
00:00:41.0 --> 00:00:44.0
Ah, and that added a nice long branch across.

10
00:00:44.0 --> 00:00:47.0
And remember, you will almost always have 

11
00:00:47.0 --> 00:00:52.0
the branch of the neuron going from one side of the cube to the other; 

12
00:00:54.0 --> 00:00:57.0
they don't usually end in the middle.

13
00:01:00.0 --> 00:01:03.0
Okay, so there's something interesting going on here:

14
00:01:03.0 --> 00:01:07.0
Note that the line looks like it goes right here, the outline . . .

15
00:01:07.0 --> 00:01:09.0 
Let me hit shift and I'll show you.

16
00:01:09.0 --> 00:01:11.0
So clearly there's an outline here, 

17
00:01:11.0 --> 00:01:14.0
but it looks like the AI has made a mistake 

18
00:01:14.0 --> 00:01:16.0
and has colored this in as well.

19
00:01:16.0 --> 00:01:18.0
And if we look at it in the 3D, 

20
00:01:18.0 --> 00:01:21.0
we might be able to see it pretty well.

21
00:01:24.0 --> 00:01:28.0
Ah, there we go, see how this is jagged here? 

22
00:01:28.0 --> 00:01:31.0
That either indicates that that there's something missing, or there's a merger, 

23
00:01:31.0 --> 00:01:34.0
or there's something missing off of the merger.

24
00:01:34.0 --> 00:01:36.0
So what we want to do is ---

25
00:01:36.0 --> 00:01:39.0
This is the correct one, this is the dark blue part, here.

26
00:01:39.0 --> 00:01:41.0
So that's the seed piece we started with, 

27
00:01:41.0 --> 00:01:44.0
we want to continue tracing the piece that is correct 

28
00:01:44.0 --> 00:01:47.0
and ignore the mistake that the AI made.

29
00:01:47.0 --> 00:01:50.0
What we're going to do is focus on the good part 

30
00:01:50.0 --> 00:01:53.0
and ignore the stuff that's over the edge.

31
00:01:53.0 --> 00:01:56.0
We don't want to continue the mistake, okay.

32
00:01:56.0 --> 00:01:59.0
Alright, so it looks like we passed it, 

33
00:02:00.0 --> 00:02:03.0
and we can continue on now.

34
00:02:03.0 --> 00:02:06.0
When there is a merger, it's not usually a huge problem --- 

35
00:02:06.0 --> 00:02:09.0
you just want to make sure you don't make the problem worse.

36
00:02:09.0 --> 00:02:12.0
Alright, I want to follow this little piece that goes up here.

37
00:02:15.0 --> 00:02:18.0
Okay, it looks like it might go this way.

38
00:02:19.0 --> 00:02:22.0
Oops, and that's me accidentally clicking on something.

39
00:02:22.0 --> 00:02:25.0
Let's deselect that, so right-click, right-click,

40
00:02:25.0 --> 00:02:29.0
and don't worry, that happens every once in a while.

41
00:02:35.0 --> 00:02:39.0
Looks like that one disappears, so now we need to check the other branch.

42
00:02:43.0 --> 00:02:47.0
We can see in the 3D that there's another branch going down.

43
00:02:47.0 --> 00:02:49.0
and I want to make sure we check both of them,

44
00:02:53.0 --> 00:02:58.0
so it looks like this lower one actually continues.

45
00:03:12.0 --> 00:03:14.0
Okay, it looks like that one ends.

46
00:03:14.0 --> 00:03:18.0
Now we need to go back and check the rest of this branch, because we didn't do that,

47
00:03:18.0 --> 00:03:22.0
and the easiest way to do that is to double-click in the 3D.

48
00:03:22.0 --> 00:03:26.0
And that is going to take you in the 2D to where you double-clicked in the 3D.

49
00:03:26.0 --> 00:03:29.0
I can see right here that there are some pieces missing,

50
00:03:29.0 --> 00:03:31.0
let's start coloring those in.

51
00:03:51.0 --> 00:03:54.0
Alright it's splitting in two, so I'm going to follow the lower one first.

52
00:04:00.0 --> 00:04:02.0
Okay, so we've reached the end of that.

53
00:04:02.0 --> 00:04:04.0
Let's scroll back until they join.

54
00:04:04.0 --> 00:04:06.0
And now we're going to follow the second one.

55
00:04:06.0 --> 00:04:08.0
Remember, you only want to follow one at a time.

56
00:04:08.0 --> 00:04:11.5
Okay so this is going up here probably.

57
00:04:11.5 --> 00:04:13.5
Let's hit shift to take away the color, 

58
00:04:13.5 --> 00:04:15.5
and yep, there's no outline.

59
00:04:15.5 --> 00:04:18.0
So let's continue coloring that in.

60
00:04:23.0 --> 00:04:25.0
Alright, and we've reached the edge of the cube.

61
00:04:25.0 --> 00:04:27.0
Very good, we're finished.
