刚刚收到项目方的群体邮件,除了简述近期R@H计算程序的更新外,主要就是介绍CASP7并鼓励大家多多参加R@H!

另外,项目方正在努力降低计算程序的内存占用,希望能控制在100M之内(对于150个氨基酸组成的蛋白质)。

We are sending out a newsletter that was written by the volunteers to all participants whose preferences allow (so, no, we've not become a SPAM host). The letter outlines the upcoming CASP contest and our greater need for computing power during that time. Sending out newsletters will be a very rare event - primarily because it is a big pain.

我们正在发送一封邮件通讯给那些愿意接收我们邮件的参与者。邮件中概述了即将到来的CASP竞赛以及我们对计算能力的渴求。另外,我们并不会经常发送这样的邮件通讯。

If you have seen any slowdowns in other computer applications when rosetta@home 5.12 is running, please post here. We are testing a potential fix on ralph, if you wish to help out!

如果你在运行5.12版本的计算程序时碰到了计算机变慢的情况,请在下面的帖子中报告。我们正在RALPH项目中测试一个可能有用的修复。

CASP7的第一个预测对象已经发布,大概明天之后就会开始分发相关的任务包了。

The first CASP 7 target was released today!

Here is its amino acid sequence:

MSFIEKMIGSLNDKREWKAMEARAKALPKEYHHAYKAIQKYMWTSGGPTDWQDTKRIFGG
ILDLFEEGAAEGKKVTDLTGEDVAAFCDELMKDTKTWMDKYRTKLNDSIGRD

can you tell from this what the three dimensional structure and function of this protein are?

The problem with proteins, of course, is that you can't read off directly from the sequence what the structure and function are, although both are completely determined by the sequence (the genetic blueprint, quite literally).

We are excited because this protein looks unrelated to any protein of known structure, and is not too much bigger than most of the proteins we've running tests on these many months, so it is a perfect challenge for the methods we've been developing. After some quick runs on RALPH to make sure work units behave properly, you should see work units for this protein by the end of tomorrow!

Rosetta@home has been updated to 5.16. In addition to matching the date, the new app has slightly lower memory requirements and includes some improvements that will allow us to test different science protocols. More info here.

计算程序升级到5.16。除了和日期对应(汗...),新版本对内存的占用稍有降低,算法上也有改进。详细请看这里

Rhiju and I had fun looking at the lowest energy structures returned for T283 thus far. They are very similar in the first two thirds of the protein, but for the last third we see several distinct solutions. Based on our experience with the test problems over the past three months, we expect that with more sampling one of the solutions will clearly win out, and this should be (we hope!) the correct structure.

Thus far we have about 100,000 structures returned; we hope to have 10x more sampling before submitting predictions.

We made another step forward today in reducing the rosetta memory footprint. For a 175 amino acid residue protein, the standard ab relax protocol we are using for CASP took 222MB of virtual memory three weeks ago, and is now down to 108MB! Now a computer with only 256MB of memory should be able to comfortable process rosetta@home jobs even for larger proteins. The major memory hog now is the boinc graphics which can add on another 100MB or more--any experts out there who might be able to help with this? In any event, you should be able to run rosetta@home on low memory machines as long as you turn the graphics off.

A side benefit to some of the memory use reductions is that it should be relatively easy to reduce the sizes of some of the input files we send out with each work unit. Would a 30% reduction make a significant difference to dialup users?

Seven targets have been released thus far in CASP7. The list, which is updated daily, is at
http://predictioncenter.gc.ucdav ... er.org;page=casp7/.

175个氨基酸组成的蛋白质,三周前的老程序需要222M内存,现在的程序只需要108M!

最近动作平凡。估计是前段时间主管被鼓励了,现在更加要屁颠屁颠卖力了。

主要原因应该是CASP7吧?
