» Description

In the Correlations section, pairwise correlation of gene expression levels can be calculated and represented.

Correlation is a technique for investigating the relationship between two quantitative, continuous variables. Values of the correlation coefficient are always between -1 and +1. A correlation coefficient of +1 indicates that two variables are perfectly related in a positive linear way, a correlation coefficient of -1 indicates that two variables are perfectly related in a negative linear way, and a correlation coefficient of 0 indicates that there is no linear relationship between the two variables.

Specifically, this option of CANCERTOOL provides the results in two different modalities:

  • In the summary option, the output is a compressed folder with PDF files containing gene expression pairwise correlation analyses graphs in the datasets corresponding to the histological cancer selected.
  • In the custom, the output is individual editable figures in big size for the selected sections, together with the raw data employed and statistical analysis in plain text.

    • Please, if you have any doubt, check the manual.
