    Data

    All genomic data is selected by default. Select from the list any list that has been created for this study.

    cls

    Select any annotation field.
    The CLS file format defines phenotype (class or template) labels and associates each sample in the expression data with a label. It uses spaces or tabs to separate the fields. The CLS file format differs somewhat depending on whether you are defining categorical or continuous phenotypes:
    Categorical labels define discrete phenotypes; for example, normal vs tumor).
    Continuous phenotypes are used for time series experiments or to define the profile of a gene of interest (gene neighbors).

    Info
    titleNote

    Most GenePattern modules are intended for use with categorical phenotypes. Therefore, unless the module documentation explicitly states otherwise, a CLS file should define categorical labels.

    Filter Flag

    Variation filter and thresholding flag

    Preprocessing Flag*

    Discretization and normalization flag

    Min Change*

    Minimum fold change for filter

    Min Delta*

    Minimum delta for filter

    Threshold*

    Value for threshold

    Ceiling*

    Value for ceiling

    Max Sigma Binning*

    Maximum sigma for binning

    Probability Threshold*

    Value for uniform probability threshold filter

    Num Exclude*

    Number of experiments to exclude (max & min) before applying variation filter

    Log Base Two

    Whether to take the log base two after thresholding; default setting is "Yes".

    Number of Columns Above Threshold*

    Remove row if n columns are not >= than the given threshold
    In other words, the module can remove rows in which the given number of columns does not contain a value greater or equal to a user defined threshold.

    Test Direction*

    The test to perform (up-regulated for class0; up-regulated for class1, two sided). By default, Comparative Marker Selection performs the two-sided test.

    Test Statistic*

    Select the statistic to use.

    Min Std*

    The minimum standard deviation if test statistic includes the min std option. Used only if test statistic includes the min std option.

    Number of Permutations*

    The number of permutations to perform. (Use 0 to calculate asymptotic P-values.) The number of permutations you specify depends on the number of hypotheses being tested and the significance level that you want to achieve (3). The greater the number of permutations, the more accurate the P-value.
    Complete – Perform all possible permutations. By default, complete is set to No and Number of Permutations determines the number of permutations performed. If you have a small number of samples, you might want to perform all possible permutations.
    Balanced – Perform balanced permutations

    Random Seed*

    The seed for the random number generator.

    Smooth P-values

    Whether to smooth P-values by using the Laplace's Rule of Succession. By default, Smooth P-values is set to Yes, which means P-values are always less than 1.0 and greater than 0.0.

    Phenotype Test*

    Tests to perform when class membership has more than 2 classes: one versus-all, all pairs.
    Note: The P-values obtained from the one-versus-all comparison are not fully corrected for multiple hypothesis testing.
