   - In the upper-right part of the visualization tool, all selected pathways from the differential signaling form are shown along with one or two arrows. These arrows indicate whether in one of the "Effector circuit" within each pathway a differential activation pattern between the two compared groups have been found.\\ The arrows will be colored if the differential activation is significant after the p-value adjustment (or unadjusted p-value, if the "Unadjusted" parameter has been selected) and depicted in grey if it isn't.\\ The arrow will point up or down if an up-regulation or down-regulation of the signal occurs between the circuits within that pathway.\\ The meaning of this up or down-regulation depends on the comparison performed, that normally would be case vs. control (comparison between selected class from the design file : condition 1 Vs condition 2).\\ Only one arrow is shown if all the effector circuits are whether up or down-regulated.{{ ::pathwaysreport2.png?nolink |}}
-  -  In the lower-right part of the tool will appear all the circuits in which a pathway (previously selected on the upper part -1-) can be decomposed. Once any of the circuit is clicked the nodes and interactions (edges) that form part of this circuit are highlighted in the pathway viewer (), One example might be the red-highlighted circuit on the figure below.{{ ::effectorcircuithl.png?nolink |}}

   - In the visualization part there are two types of objects, the nodes and the edges.{{ ::pathwaysreport3.png?nolink |}}
-    * The nodes represent the different proteins or metabolites that are responsible on passing the signal from the previous node to the next one. As commented before, the nodes can be plain or complexes. In the former it is only necessary the presence of one protein (although that same function can be done by several proteins), while in the complex ones it is necessary the presence of two or more proteins to pass the signal through.\\ The color on the nodes are the result of a differential expression analysis on the gene/s involved on performing that node's function.

     * The edges represent how the interactions between the different nodes are.\\ If the edge is an arrow then the previous node will be activating the next one, while if it ends with a vertical bar is the former node will inhibit the functionality of the following node. This interactions may be depicted in red or blue depending on the circuit they form part of (whether they are up-regulated or down-regulated). It may occur, that two or even three colors for a same edge are shown, but this only happens when a circuit is not yet selected on the lower-right part of the tool.\\ Once an certain circuit is selected all its edges will be colored in the same color depending on the result of the differential signaling activation analysis.{{ ::pathwaysreport4.png?nolink |}}

   * The first section below there is a link to download the calculated circuit activity values. This matrix file indicates for each effector circuit the level of activation calculated using Hipathia method for each sample.{{ ::circuitvalue.png?nolink |}}
   * The Heatmap plot represented on the hipathia results page is a heatmap of the activation values from the most differentiated effector circuits (rows) between groups along with a clustering of the samples (columns). This plot allows to observe if its possible to differentiate the groups that are compared according to its effector circuit activation values.\\ The colors depicted here indicates the level of activation for the different circuit in each sample, being the bluish ones those with lower activation levels and the reddish the highest ones (e.g. if a given cell of the heatmap is blue would indicate that this particular effector circuit is poorly activated in that determined sample) {{ ::heatmap.png?nolink |}}
