and was used to generate all model results in [1,2]. A selection of results supporting [1] are included. By releasing this code, other researchers can independently verify results. The model implemented in this software is described both in [1,2].
This software has dependencies on some common libraries, which need to be installed first. Instructions for installation and running are found below.
email: fdannenberg/live/nl
Unzip the folder. The software depends on the following libraries that you should install. Dir lib/ should contain
- commons-math3-3.0.jar or equivalent http://commons.apache.org/
- jgrapht-jdk1.6.jar or equivalent http://jgrapht.org/ do not confuse with jgraph
- junit-4.12.jar or equivalent http://junit.org/
In addition, the plotting scripts require R to run. http://www.r-project.org/
javac -cp lib/jgrapht-jdk1.6.jar:lib/commons-math3-3.0.jar src/folding/*.java src/writers/*.java src/plotting/*.java -d bin;
THREADS=8 PATHS=20 RATE=0.4; DESIGN0="design23eAll" DESIGN1="design23eAllEnergy" DESIGN2="methodsPaperAllPlots" DESIGN3="methodsPaperNoCooperativity";
THREADS # number of simulation threads
PATHS # number of folding pathways simulated per thread
RATE # temp drop in celsius per minute (rate)
DESIGN0="design23eAll" # runs 5 different designs
DESIGN1="design23eAllEnergy" # runs same designs with sequence-specific domain stability
DESIGN2="methodsPaperAllPlots" # methods paper plots and data
DESIGN3="methodsPaperNoCooperativity" # special SI table in the methods paper
java -cp bin:lib/jgrapht-jdk1.6.jar:lib/commons-math3-3.0.jar -Xmx4000m folding.Control $DESIGN0 "distance" $THREADS $PATHS $RATE;
Correct calls will output to the commandline something similar to the below, at which point the simulation starts to run. After the run, output is placed in the /output/ dir.
