Color Mappings in ProMeTra

• ProMeTra visualizes numerical values from Omics-experiments by mapping them onto

several predeined color gradients (e.g. Red-to-Green, Yellow-to-Blue, etc). Elements representing transcripts, proteins, or metabolites in !Pathway- or GenomeMaps are highlighted with the respective colors. The following ColorLegend shows an M-value mapping that can for example be used for Transcriptomics datasets.

• Various color gradients have been defined and are available via the web interface.

• Users can select the numerical range of the color gradient mapping. Experimental values that

are outside the range will be mapped to the colors at the respective end of the gradient. Alternatively, an automatic computation of maximal and minimal values can be employed. The color gradient range is then dynamically adapted to the submitted experimental data.
