Introduction
In addition to the graphical user interfaces, via a web-browser, all SOCR Analyses allow command-line shell execution on local systems.
General Usage
- Get the latest SOCR JAR files from the SOCR page (http://socr.ucla.edu/htmls/jars/).
- The command-line interface to SOCR Analyses generally uses EXAMPLE 1 from the list of example data files for the corresponding analysis.
- All Input files are ASCII (see examples within each of the specific analyses).
- a -h flag at the end of the command-line indicates that the first row in all ASCII input data files is a HEADER row (so it's not interpreted as data)
Two Independent Sample T Test Usage
- Generic Setting:
java -cp [SOCRjar_location]/SOCR_core.jar:[SOCRjar_location]/SOCR_plugin.jar edu.ucla.stat.SOCR.analyses.command.TwoPairSignedRankCSV [data_location]/rank1.txt [data_location]/rank2.txt -h
- Example: Edit a new file (ChiSquareModelFitCSV.csh) using any editor and paste this inside (make sure the file has executable permisions). Some operating systems/platforms may require variants of this (C-shell) script.
#!/bin/csh
date
java -cp /cxfs/ccb/CCB_SW_Tools/others/Statistics/SOCR_Statistics/bin/SOCR_core.jar:/

Example Input data files
Two test datafiles are included with the SOCR analyses command-line distribution (rank1.txt and rank2.txt). The ASCII content of each of these is included below. Note that the first lines in these files are column headers. This requires the "-h" flag at the end of the command line execution so that these first lines are interpreted as column headers.

| 27.0 | 25.0 |
| 29.0 | 25.0 |
| 37.0 | 27.0 |
