Why does F@H fold the same prteins over and over and...

Well, the topic is my question, pretty simple.

I run F@H in screensaver mode, which allows you to see which protein it is folding, how much progress you have made on the WU, etc. I found it curious though that I am on proteinA for the third time that I can remember. Anyone know what's up with that?

Different parts of the animation. One single protein fold animation, done beginning to end on one PC, would take years, IIRC. It may seem to be the exact same protein, but it's more likely you're seeing parts 137, 141, and 165 of 11000 in the series.

The main F@H page has a results page with all the finished animations, kind of cool to look at.

Well, I didn't mean to imply that it was the same protein b/c I was staring at the picture, nor that I was trying to watch it 'fold' In the screensaver version the name of the protein is written on the side of the screen. I am not talking about frames though, but the fact that this is the third (or more) time I have been on proteinA. I understand each WU has multiple frames, and frames are the 1-100 (or whatever) that get counted toward a WU progress.

Forge's explanation makes sense, but I think he should use the word 'run' (as in: each protein has multiple runs.) Look in your logfile at the start of a WU to see what I mean.

From the Folding @ Home FAQ:

I just finished a WU and now I got another for the same protein. Is there something wrong?

No, most likely everything is fine. We're studying the dynamics of a few proteins, so you're likely to get the same protein to work on multiple times. Each WU gives us additional information about the dynamics of that protein, so it is important to us. Indeed, if we did only 1 WU per protein, we would not learn very much.

So in other words, it's supposed to do that. Just checked my stats and I've done 125 WU's of Protien A myself...

If I remember right, each WU computes a 5ns section fo the protein folding... so you will get the same protein many many times...

I too have been wondering the same thing as I look at my standings on F@H ,
