The LINUS distribution is a suite of programs for exploring conformational ensembles of peptides and proteins. The core of LINUS is a torsion angle Monte Carlo simulation application that allows a restrained Monte Carlo move set with a simple atomic interaction energy acceptance criterion.

You may download the complete distribution as a gzipped tar archive by clicking on the link to the left. The distribution contains a copy of the User Manual in html format. If you would just like to peruse the User Manual click on the Documentation link to the left.

LINUS is written entirely in Python although some routines are also provided as C code. The C routines will be called if they are compiled but they are not necessary.

References describing the use of LINUS are given in the reference list included with the distribution. In addition, there will be an article forthcoming in Methods and Enzymology. If you would like a manuscript version of that article please contact George Rose by email grose@jhu.edu.

LINUS was ported to Python with the goal of making a set of modules that would be useful for computational experimentation by a knowledgable user. It is not distributed as a black box program with set protocols. We find these modules very useful for answering "what if" questions about protein conformational diversity and we hope that the suite will be useful to others.

Please consider this distribution of LINUS as a suite of tools for your own implementation, modification and exploration. This distribution comes with a caveat. Our small lab is not able to respond adequately to requests for assistance, and therefore we have done our best to provide documentation. We hope you will find this documentation to be sufficiently useful.
