We used a method derived from the method described in the paper by Feng Zhang<sup>[http://www.nature.com/nbt/journal/v31/n9/abs/nbt.2647.html ZhangFgRNA]</sup>.

We first extracted all conserved regions from the NIH HIV-1 Reference Genome. In this step, we found around 10 alternatives for the next process. Here all screening processes are done in a per-strain basis because of the high mutability of the HIV-1 virus.

Method

We used a method derived from the method described in the paper by Feng Zhang[http://www.nature.com/nbt/journal/v31/n9/abs/nbt.2647.html ZhangFgRNA].


Conserved Sequence Analysis

We first extracted all conserved regions from the NIH HIV-1 Reference Genome. In this step, we found around 10 alternatives for the next process. Here all screening processes are done in a per-strain basis because of the high mutability of the HIV-1 virus.

Strip out sequences without PAM
