A Downloadable, Portable and Versatile Software Package

We have developed a standalone software package for generating SMOG models. This is a nearly complete re-write of the original SMOG software. The original models are still provided, though the files may look a bit different. While the SMOG web-based interface will continue to be available, the standalone code is particularly useful if you want to modify the forcefield (e.g. include new residues, design a new variant, etc). We would like to express our gratitude to all of the Beta testers. Based on your feedback, we have extensively tested the code and have tried to make it easy to use. Since we will continue to develop the software, your continued feedback is always appreciated.

Manuscript: The manuscript describing SMOG 2 is available in PLOS Computational Biology. It can be found here.

Mailing list: To stay up to date with new developments, as well as follow and participate in discussions about SMOG models, you can sign up for the smog-users mailing list.

Getting Help: Please direct questions and comments to While we have made our best efforts to provide informative error messages, if you receive a cryptic message (e.g. "uninitialized" variables), please let us know so that we may help.

SMOG CHECK (Test suite): It is strongly recommended that you verify your installation of SMOG is working properly on your machine. We have prepared a set of test scripts to verify that SMOG is generating appropriate models. These checks are version-specific.

Within the bundle you will find a shorter sanity test called quick-check and a very comprehensive set of tests called smog-check, which can take up to an hour to complete. We are continually adding more tests to these scripts.

If your environment is configured properly for smog2 (i.e. when you type smog2 it prints the smog2 splashtext) then the checks can be run simply by:
>$ cd [smog-check-directory]
>$ ./quick-check
...quick-check output...
>$ ./smog-check
...smog-check output...

Forcefield Repository: One of the key features of SMOG 2 is that the forcefields are portable. That is, you can share new models by simply making your template files available. While there are multiple forcefields that are included in the default distribution, you may share your user-developed forcefields via this website. If you would like to have your forcefield made available, please contact us.

Version History for SMOG 2: SMOG 2 updates will be documented here. The version history for the Shadow Contact Map can be found elsewhere. Since new versions occasionally have bug fixes, it is highly recommended that you only use the most recent released version. If you would like to test out the newest options available, then you may be interested in trying the beta version.
