Input | |
Expression data | Input file in seltag format |
Fields select |
List of fields -
List of expression fields (tissues) used to calculate correlation between gene expression profiles,
namely field indices in data format of input file starting from 1 (column numeration is not depend on
the Case Names option).
Examples of input: 1;2;3-7;12; 1-12; Selection data - Filename for fields selection in XML format. This is another way to set the list of fields. |
Genes for select | List 1 of genes
- List of genes to calculate correlation, namely gene indices in data set of input file starting from 1
(column numeration is not depend on the Case Names option).
Examples of input: 1;2;3-7;12; 1-12; Gene list 1 - Filename for genes selection in XML format for Gene List 1. This is another way to set the list of genes. |
Genes for comparison | List 2 of genes
- List of genes to calculate correlation, namely gene indices in data set of input file starting from 1
(column numeration is not depend on the Case Names option).
Examples of input: 1;2;3-7;12; 1-12; Gene list 2 - Filename for genes selection in XML format for Gene List 2. This is another way to set the list of genes. |
Output | |
Result | Name of output file |
XML data | Name of the file for graphical output of correlation coefficient value profiles. If not specified then no graph output assumed. |
Title | User-specified title of the graph plot. |
Author | User-specified name of the graph author. |
Comment | User-specified graph additional commentary line. |
X axis name | User-specified graph X axis name. |
Y axis name | User-specified graph Y axis name. |
Options | |
Type of correlation | Type of correlation coefficient. Three types of correlations are possible: Pearson's r, Spearman rank correlation and Kendall tau correlation. |
Correlation threshold type | Type of threshold to select best correlating gene pairs. Several options are possible: Best N correlations ; Best % correlations; Correlation coefficient value; Select all pairs. |
Correlation threshold value | Threshold to select genes from List 1 on the basis of the their correlation coefficient value to genes from List 2. |
Missing data treatment | Option to treat missing data. Several options are possible : Substitute by means (missing data are substituted by expression means in corresponding field); Case-wise deletion (correlations/distances are calculated by excluding cases that have missing data for any of the selected variables, all correlations are based on the same set of data); Pair-wise deletion (correlations/distances between each pair of profiles are calculated from all fields/samples having valid data for those two profiles). |
