[OpenWorm](http://openworm.org) aims to build the first comprehensive computational model of *Caenorhabditis elegans* (*C. elegans*), a microscopic roundworm. With only a thousand cells, it solves basic problems such as feeding, mate-finding and predator avoidance. Despite being extremely well-studied in biology, a deep, principled understanding of the biology of this organism remains elusive.

We are using a bottom-up approach, aimed at observing the worm behaviour emerge from a simulation of data derived from scientific experiments carried out over the past decade. To do so, we are incorporating the data available from the scientific community into software models. We are also forging new collaborations with universities and research institutes to collect data that fill in the gaps.

- Open a terminal and run `./run-shell-only.sh` (or `run-shell-only.cmd` on Windows). This will let you log into the container before it has run `master_openworm.py`. From here you can inspect the internals of the various checked out code bases and installed systems and modify things. Afterwards, you'll still need to run `./stop.sh` to clean up.
69
66
- If you wish to modify what gets installed, you should modify `Dockerfile`. If you want to modify what runs, you should modify `master_openworm.py`. Either way you will need to run `build.sh` in order to rebuild the image locally. Afterwards, you can run normally.

The Docker container is a self-contained environment in which you can run OpenWorm simulations. It's fully set up to get you started by following the steps above. At the moment, it runs simulations and produces visualizations for you, but these visualizations must be viewed outside of the Docker container. While you do not need to know much about Docker to use OpenWorm, if you are planning on working extensively with the platform, you may benefit from understanding some basics. [Docker Curriculum](https://docker-curriculum.com) is an excellent tutorial for beginners that is straightforward to work through (Sections 1 - 2.5 are plenty sufficient).

Yes, but it is marginally more complex. The easiest way is to modify anything in the Docker container once you are inside of it - it will work just like a bash shell. If you want to modify any code in the container, you'll need to use an editor that runs in the terminal, like nano. Once you've modified something in the container, you don't need to re-build. However, if you run `stop.sh` once you exit, those changes will be gone.

The simulation by default outputs only a few figures and movies to your home system (that is, outside of the Docker container). If you want to access the entire output of the simulation, you will need to copy it from the Docker container.

For example, say you want to extract the worm motion data. This is contained in the file `worm_motion_log.txt`, which is found in the `/home/ow/sibernetic/simulations/[SPECIFIC_TIMESTAMPED_DIRECTORY]/worm_motion_log.txt`. The directory `[SPECIFIC_TIMESTAMPED_DIRECTORY]` will have a name like `C2_FW_2018_02-12_18-36-32`, and its name can be found by checking the `output` directory. This is actually the main output directory for the simulation, and contains all output, including cell modelling and worm movement.

Once the simulation ends and you exit the container with `exit`, but before you run `stop.sh`, run the following command from the openworm-docker-master folder:
This will copy the file from the Docker container, whose default name is `openworm`. **It is crucial that you do not run `stop.sh` before trying to get your data out (see below)**

When you are in the Docker Container `openworm`, and are done interacting with it, you type `exit` to return to your system's shell. This stops execution of anything in the container, and that container's status is now `Exited`. If you try to re-start the process using `run-shell-only.sh`, you will get an error saying that the container already exists. You can choose, at this point, to run `stop.sh`. Doing so will remove the container and any files associated with it, allowing you to run a new simulation. However, if you don't want to
