Hi guys, this is Rachel, or rprentki, here with the second tutorial video for EyeWire.

2
00:00:05.5 --> 00:00:10.0
Now that you have a bit of experience, we're going to show you how to use the advanced features of the 3D.

3
00:00:10.25 --> 00:00:11.25
Let's get started.

4
00:00:12.0 --> 00:00:21.0
Alright, so if you forget any of the commands we're about to teach you, you can always go find them if you click on the question mark in the lower right hand corner, down here.

5
00:00:23.333 --> 00:00:28.0
So the AI has started coloring a neuron for us, and soon we're going to get the chance to find what it missed.

6
00:00:29.0 --> 00:00:39.6
Alright, so here's a hint, try clicking on what seems to be the missing piece right here, and, well, it showed up red, so that's not a good sign. 

7
00:00:39.7 --> 00:00:46.3
While you're early on in the tutorial, stuff that you can select incorrectly is going to show up as red, and the correct stuff is going to show up as green.

8
00:00:46.6 --> 00:00:52.0
Now, if we look at it in the 3D, it's really obvious that this red thing does not belong.

9
00:00:52.25 --> 00:00:58.3
And you can see it also in the 2D; this giant red thing got added when we just clicked on this tiny little piece right here.

10
00:01:01.5 --> 00:01:06.5
And once again, it's really far away but that's because this red piece happens to be connected to that red piece.

11
00:01:07.0 --> 00:01:09.0
So this is clearly not what we wanted.

12
00:01:09.5 --> 00:01:13.0
And it's advising us to look at the 3D, which we already did.

13
00:01:13.5 --> 00:01:19.0
So if you ever add something and it pops up as something huge, that you notice in the 3D or 2D, not a good sign, usually.

14
00:01:20.0 --> 00:01:27.0
Now if we want to rotate the cube to the left, the 3D, click and drag.

15
00:01:27.6 --> 00:01:31.5
Notice how it forms an 'X' shape where the blue is going this way, and the red is going across.

16
00:01:31.5 --> 00:01:35.5
This is a really unnatural shape, and neurons don't take that.

17
00:01:35.5 --> 00:01:40.0
Also notice how the blue one is really smooth, and the red one is kind of jagged, with little bulges.

18
00:01:41.0 --> 00:01:51.0
Usually what you're going to see in the cube is stuff that looks similar, so if this blue one, our start piece, is nice and smooth, what we add to it should be pretty smooth as well.

19
00:01:53.0 --> 00:01:55.6
So the red piece is a mistake, and we're going to get rid of it.

20
00:01:55.6 --> 00:01:58.0
To get rid of it you right-click.

21
00:01:58.0 --> 00:02:02.0
Okay, now let's go find the pieces that the AI actually missed.

22
00:02:02.0 --> 00:02:04.6
When we finish, we're going to hit "Check my work" to see we did. 

23
00:02:04.6 --> 00:02:08.0
So we know that this piece isn't good, let's see how this one is.

24
00:02:08.0 --> 00:02:10.3
Alright, and it's green, so we're doing well.

25
00:02:10.3 --> 00:02:13.0
And lets scroll a little bit.

26
00:02:13.0 --> 00:02:15.0
Clicking to pick up the pieces.

27
00:02:16.0 --> 00:02:17.0
Okay.

28
00:02:45.0 --> 00:02:50.0
Oops, and that's me mis-clicking on something, so I'm going to deselect that.

29
00:02:54.5 --> 00:02:59.0
Okay, so I can see from the progress bar down here that we're close, but we're not done yet.

30
00:02:59.0 --> 00:03:02.6
You can notice that there's a little bit blank right here, so that means we've missed something.

31
00:03:02.6 --> 00:03:05.0
So we've got to go back and try and find it.

32
00:03:06.0 --> 00:03:12.0
Okay, so I'm scrolling along and I don't see . . . ah, here we go, up here.

33
00:03:17.0 --> 00:03:21.0
Okay, it looks like we've found about everything, let's hit "Check my work."

34
00:03:21.6 --> 00:03:23.0
100% correct!

35
00:03:23.0 --> 00:03:26.0
Excellent, we're ready to move onto the next one.
