fids_to_coexpressed_fids

The routine fids_to_coexpressed_fids returns (for each input fid) a list of features that appear to be coexpressed. That is, for an input fid, we determine the set of fids from the same genome that have Pearson Correlation Coefficients (based on normalized expression data) greater than 0.5 or less than -0.5.

Example:

fids_to_coexpressed_fids [arguments] < input > output

The standard input should be a tab-separated table (i.e., each line is a tab-separated set of fields). Normally, the last field in each line would contain the identifer. If another column contains the identifier use

-c N

where N is the column (from 1) that contains the subsystem.

This is a pipe command. The input is taken from the standard input, and the output is to the standard output.

Documentation for underlying call

This script is a wrapper for the CDMI-API call fids_to_coexpressed_fids. It is documented as follows:

$return = $obj->fids_to_coexpressed_fids($fids)

Parameter and return types

$fids is a fids
$return is a reference to a hash where the key is a fid and the value is a scored_fids
fids is a reference to a list where each element is a fid
fid is a string
scored_fids is a reference to a list where each element is a scored_fid
scored_fid is a reference to a list containing 2 items:
	0: a fid
	1: a float

Command-Line Options

-c Column

This is used only if the column containing the subsystem is not the last column.

-i InputFile [ use InputFile, rather than stdin ]

Output Format

The standard output is a tab-delimited file. It consists of the input file with extra columns added.

Input lines that cannot be extended are written to stderr.
