Re-examining my List of Data

Post by oscar »

I have ID'd 23 movies out of about 1200 viewed as having a possible track (or some strange thing). However upon re-examination I must conclude the following:

Nine of the movies have the strange "spots" that come into focus below the surface :?

Eleven where incorrect ID's due to focus issues :oops:

One movie...well I have no idea why I thought I saw something :lol:

Movie 6095503V1 has a strange slash-like thing below the surface :?:

And last but not least...Movie 6880717V1 has a track :!:

I really hope that's a track but I wouldn't jump to conclusions either. Nearby there is a perfectly focused section of gel which that ball could very well be a part of. Also, while it does look like a large grain below the surface, I still don't see a hollowed out tube leading down to it like in the calibration movies. One might guess that a granule that large would leave an even larger track.

Gee Geckzilla, I do believe you are correct.
Movie 6880717V1 may not have a track after all.
I really need to be more discerning.

But Oscar, you've done well to only have 23 out of 1200, some people have said they are into triple figures, which means there is a lot of chaff in the data!
But I am the same.. out of eight I have two which I am convinced are tracks:
Movie 305392V1
Movie 6355541V1
both lateral..
and the rest are :oops: or browser hysterics...
Cheers

I have found the same thing looking back on my earlier movies, I guess as we all get more experience we will find better looking track candidates.

Belinda, I can add two more movies with the same dot in position [350, 40] microns. 350 microns from left to right, 40 microns from bottom to top.
Final list:
305392V1
6355541V1
5553236V1
4911902V1

What is it? Microscope problem?

PS. 4236471V1 - the fifth.

I wouldn't worry too much about marking something that turns out not to be a track. We need to be very much geared toward "in case of doubt, mark it." Looking into something that turns out to be not what we're looking for is a waste of time, but missing one of the few particles expected to be captured would be a tragedy.
If you're going to be just like everyone else, what's the point in existing?

Is there any way to unmark a movie? As I've been reviewing the early movies I marked I'll admit I don't think I see any thing or I should say if I were to view it again I would probably mark no track
