YYC for file version control system is a DNA storage codec algorithm suitable for encoding files in different versions. It is adjusted based on YYC. It can transcode two adjacent binary sequences into one DNA sequence, and only recode the modified parts of each version file. This algorithm can help to achieve a high-density, high-feasibility DNA storage of multi-version files based on DNA synthesis.

Environment Configuration

The kit is developed by Python3.9.

In addition, the packages we are calling now is as follows:

• sys
• os
• random
• math
• copy
• struct
• datetime
• pickle
