So you might ask, well, why do we need to use computational methods in the first place?

你可能会问 为什么我们一开始就需要使用计算方法呢？

All of this data was then plugged into three different algorithms, which all used slightly different computational methods to categorize the data they were given.

所有这些数据随后被插入到三种不同的算法中，这些算法都使用了略微不同的计算方法来对给出的数据进行分类。

Scientists wanted to know the structure of a protein-cutting enzyme produced by a retrovirus similar to HIV. They haven't been able to solve the protein structure using standard computational methods.

科学家们很想掌握由反向病毒所衍生的蛋白剪切酶的结构，而反向病毒是指，比如HIV这样的病毒。这类蛋白结构是不能通过标准算法法则推导就直接得出的。
