====== Function based analysis ======

For each of the functional analysis selected to be performed, the same descriptive statistics as in the Path values case are shown:

  * **GO terms/Uniprot keywords values**: You can download the matrix of function values by clicking on //GO terms values// or //Uniprot keywords values//.
  * **Heatmap**: A heatmap is a graphical representation of the values of a matrix. A not-supervised clustering is performed on the data per columns (samples). A good separation between the two colors of the upper bar of the heatmap indicates that the differences between the two groups are big enough to discriminate between them.
  * **PCA**: A Principal Components Analysis is performed in order to see if the matrix contains information enough to separate between the two groups. 
  * **GO terms/Uniprot keywords significance**: Ordered table of the functions significance. More significant terms are displayed in the upper part of the table. For each functional term, the following information is shown:
    * **path/term**: Name of the function.
    * **UP/DOWN**: Up when the function is up-regulated in the disease case, DOWN otherwise.
    * **statistic**: Statistic of the of the statistic test.
    * **p.value**: P-value of the statistic test.
    * **FDRp.value**: Adjusted p-value of the statistic test using the FDR method.
    * **Fold Change**
    * **logFC**
