Version 1.1b of the Short Time-series Expression Miner (STEM) ------------------------------------------------------------------------------- STEM was developed by Jason Ernst in collaboration with Ziv Bar-Joseph. Any questions about the software or bugs found should be emailed to jernst@cs.cmu.edu. The latest version of STEM will be available at www.cs.cmu.edu/~jernst/stem. Consult the file manual.pdf for comprehensive documentation about STEM. ------------------------------------------------------------------------------- STEM requires Java 1.4 or later to be installed. Java can be downloaded from http://www.java.com. ------------------------------------------------------------------------------- Once Java is installed, to start STEM in Microsoft Windows double click on stem.cmd. Otherwise to start STEM, from a command line while in the stem directory enter the command java -mx1024M -ms512M -jar stem.jar Append "-d defaults.txt" to the above command to have STEM start with its initial settings be those specified in the defaults.txt file. Note: if Java gives an error message indicating that there is not enough memory available on the computer to start STEM, then remove the -m512M option from the command. For slightly faster execution times at the expense of greater memory usage replace "-ms512M" with "-ms1024M". ------------------------------------------------------------------------------- To start STEM with default settings to analyze the sample data included in the stem directory, if in Microsoft Windows double click on the file stemGuilleminSample.cmd, otherwise from a command line while in the stem directory type the command: java -mx1024M -ms512M -jar stem.jar -d defaultsGuilleminSample.txt In the stem directory are three sample data files, g27_1.txt, g27_2.txt, and vaca.txt. The data in these files come from the Stanford Microarray Database entry http://genome-www5.stanford.edu/cgi-bin/publication/viewPublication.pl?pub_no=193 which is for the paper Guillemin, K., Salama, N., Tomplins, L., and Falkow, S. Cag pathogenicity island-specific responses of gastric epithelial cells to Helicobacter pylori infection. Proc Natl Acad Sci. USA, 99 15136-15141. The data in the g27_1.txt and g27_2.txt files are from the G27 TC1 trial 4 and G27 TC1 trial 5 time courses respectively and are technical replicates of a wildtype experiment. The data in vaca.txt is a comparison knockout experiment from the vacA trial 3 time course. ------------------------------------------------------------------------------- STEM is distributed to academic and non-profit users under a non-commercial research use license.
