This page includes the information on how to access the Multiple Linear Regression library for the purpose of computing VOLUME/IMAGE MLR analyses. Access is provided via shell-based command-line interface on local machines. More information about other SOCR Analyses command-line interfaces is available here.

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)
  • Number of variables can be indicated at the end (after -h flag). If no number of variables is specified, 3 is set as default.

Volume Multiple Linear Regression Usage

  • Generic Setting:

java -cp /ifs/ccb/CCB_SW_Tools/others/Statistics/SOCR_Statistics/bin/SOCR_core.jar:/ifs/ccb/CCB_SW_Tools/others/Statistics/SOCR_Statistics/bin/SOCR_plugin.jar edu.ucla.stat.SOCR.analyses.command.VolumeMultipleRegression -dm DesignMatrix.txt -h -regressors [name1,name2,...name_k] -dim Zmax Ymax XMax [-p PValue_Filename] [-r RValue_Filename] -data_type [1,4]

  • Options:
    • -help: print usage
    • -dm [DesignMatrix.txt]: specify a tab-separated text file containing the design matrix
    • -mask [Mask-volume.img]: specify a mask-volume (0 or 1 intensities) restricting the voxels, where the regression models are computed (optional), 1Byte Analyze format volume of the same dimensions as the data
    • -h: DesignMatrix contains a header (first row)
    • -regressors [name1,name2,...name_k]: specify which columns/variables should be used as regressors/covariates
    • -dim Zmax Ymax XMax: specify the dimension-sizes (for 2D images use ZMax=1, for 1D, Zmax=Y_Max=1
    • -p [PValue_Filename]: output the p-value volume (enter only the base of the filename)
    • -r [RValue_Filename]: output the effect-size/correlation volume (enter only the base of the filename)
    • -data_type [1,2,4]: Type=1 is for Byte, Type=2 is for Unsigned Short integer and Type=4 is for 4Byte=Float Volume Input;
  • Example: Edit a new file (VolumeMultipleRegression.csh) using any editor and paste this inside (make sure the file has executable permissions). Some operating systems/platforms may require variants of this (C-shell) script.

Example Input data files

The design-matrix datafile must be provided as tab-separated ASCII/text file (DM.txt). The ASCII content of each of these files should follow the syntax below. Note that the first lines in these files are column headers. This requires the "-h" flag on the command line at execution so that these first lines are interpreted as column headers.
