问题描述
我涉及生物学，特别DNA和常存在与来自测序基因组中的数据的大小的问题。
I am involved with biology, specifically DNA and often there is a problem with the size of the data that comes from sequencing a genome.
对于那些不具有生物学背景的谁，我会给DNA测序的快速概览。 DNA是由四个字母A，T，G，和C，它们的具体顺序的确定在细胞会发生什么。
For those of you who don't have a background in biology, I'll give a quick overview of DNA sequencing. DNA consists of four letters: A, T, G, and C, the specific order of which determines what happens in the cell.
与DNA测序技术的一个主要问题然而是，产生的数据的大小，（为一个全基因组，往往比千兆字节得多）。
A major problem with DNA sequencing technology however is the size of the data that results, (for a whole genome, often much more than gigabytes).
我知道，在C int的大小从计算机到计算机各不相同，但它仍然有超过四种选择方式更多信息存储可能性。有没有一种方法来定义一个类/方法来定义一个'基地'只占用2个或3个位？我已经搜查了定义结构，但恐怕这不是我要找的。谢谢。
I know that the size of an int in C varies from computer to computer, but it still has way more information storage possibility than four choices. Is there a way to define a type/way to define a 'base' that only takes up 2 or 3 bits? I've searched for defining a structure, but am afraid this isn't what I'm looking for. Thanks.
此外，将这项工作更好地在其他语言（可能更高水平如Java）？
Also, would this work better in other languages (maybe higher level like java)?
推荐答案
你不能只是把这些东西2 ATGC套入，然后一个字节？这样的：
Can't you just stuff two ATGC sets into one byte then? Like:
0 1 0 1 1 0 0 1
A T G C A T G C
所以这一个字节将重新present TC，AC？
So this one byte would represent TC,AC?
