Used only when genome is set to 'hg19'. - `genomeFillColor`: The color to display in each chromosome. Can be a RColorBrewer palette name used to generate one color per chromosome, or a character object or vector of character objects stating RGB values in hexadecimal format or base R colors. If the vector is shorter than the reference genome, values will be repeated. - `chrPad`: Distance between chromosomes. - `displayGenomeBorder, genomeBorderColor, genomeBorderSize`: Should the reference genome have borders? If yes specify the color, in RGB hexadecimal format, and the thickness. - `genomeTicksDisplay, genomeTicksLen, genomeTicksColor, genomeTicksTextSize, genomeTicksTextColor, genomeTicksScale`: Should the refence genome have ticks, of which length, color (in hexadecimal RGB format), with labels in which font size and color, and spaced by how many bases? - `genomeLabelDisplay, genomeLabelTextSize, genomeLabelTextColor, genomeLabelDx, genomeLabelDy, genomeLabelOrientation`: Should the reference genome have labels on each chromosome, in which font size and color? Moreover rotation and radius shifts for the label texts can be added, and the angle between the radius and the label changed. - `zoom`: Is zooming and moving in the visualization allowed? - `TEXTModuleDragEvent`: Are text annotations draggable? - `SNPMouseOverDisplay`: Display the tooltip when mouse hover on a SNP point. - `SNPMouseOverColor`: Color of the SNP point when hovered by the mouse, in hexadecimal RGB format. - `SNPMouseOverCircleSize`: Size of the SNP point when hovered by the mouse. - `SNPMouseOverCircleOpacity`: Opacity of the SNP point when hovered by the mouse. - `SNPMouseOutDisplay`: Hide tooltip when mouse is not hovering a SNP point anymore. - `SNPMouseOutColor`: Color of the SNP point when mouse is not hovering a SNP point anymore, in hexadecimal RGB format.
