** Project Goals

The project seeks to handle the checking of data files for correct syntax and
other errors before allowing the code to be uploaded.

The files are *"tab-separated"* values (TSV) files, and must conform to the
following criteria:

*** Line-Level Checks

- Must be tab-separated
-

*** Cell-Level Checks

- No empty data cells
- no data cells with spurious characters like `eeeee`, `5.555iloveguix`, etc.
- decimal numbers must conform to the following criteria:
-   - when checking an average file decimal numbers must contain exactly three places to the right side of the dot.
-   - when checking a standard error file decimal numbers must contain six or greater places to the right side of the dot.
-   - there must be a number to the left side of the dot (e.g. 0.55555 is allowed but .55555 is not).
- check line endings to make sure they are Unix and not DOS
- check strain headers against a source of truth (see strains.csv)

** Development

For reproducibility, this project is developed using guix.

To launch a guix shell for development, do:

#+BEGIN_SRC shell
  guix shell --container --network --manifest=manifest.scm
#+END_SRC

to get an environment that is isolated from the rest of your system.

*** Tests

Run tests with:

#+BEGIN_SRC shell
  pytest
#+END_SRC
