# biodatatools

biodatatools is a package that provides a collection of useful commands `biodatatools command ...`, and utility functions *biodatatools.utils* for bioinformatics analysis. 

All commands are version controlled based on `simplevc` for backward compatibility. All results are reproducible by specifying the exact command version (with a few exceptions due to the change of dependent packages and call to external tools in some commands). 

The naming convention of commands is described below. 


- check - Check for certain information or file integrity. Usually the output is not parseable
- convert - Convert file into a different format while the stored data should remain the same
- downsample - Downsample data. Input and output data type should be the same
- filter - Create a new file that retains data entries matching the criteria
- generate - Generate new file that usually serves a different purpose than the input data.
- merge - Merge multiple files storing the same data types into one file
- modify - Create a new file with certain values modified
- process - Process files from one data type into some other data type. There could be less information stored after processing
- summarize - Summarize data statistics

Certain biodatatools commands require external tools. These are not installed along with biodatatools by default. If users run a command without the required tools, biodatatools would raise an error about the missing tools.
