Highlights 定义格式

基本的格式至少要包含三列，第一列是染色体的信息，第二三列是区块的起始终止位置。色块的长度则由下面的半径参数决定。

更为清晰的定义方法：

hs1 1298972 1300443 fill_color=blue
hs1 1311738 1324571 fill_color=red,r0=0.6r,r1=0.6r+50p
hs1 1397026 1421444 fill_color=green,r0=1.1r,r1=1.15r
hs1 1437417 1459927 fill_color=green,r0=1.1r,r1=1.15r
hs1 1540746 1555847 fill_color=yellow
hs1 1560962 1645635 fill_color=purple
hs1 1624179 1645623 fill_color=grey

使用方法

• 定义半径的时候r0表示起始，r1表示终止。使用相对半径和绝对半径都是可以的。当大于1r的时候，highlight将会伸出圈外。
• Z表示层次，Z数值越大在画的时候越靠上层 下面例子同一组数据被画了3次。

<highlights>

z          = 0
fill_color = green

<highlight>
file       = data/3/genes.txt
r0         = 0.6r
r1         = 0.8r
</highlight>

<highlight>
file       = data/3/genes.txt
r0         = 0.7r
r1         = 0.75r
z          = 5
</highlight>

<highlight>
file       = data/3/genes.txt
r0         = 1.1r
r1         = 1.15r
fill_color = blue
stroke_color = dblue
stroke_thickness = 2
</highlight>

</highlights>

具体参数：

• r0 - inner radius of highlight
• r1 - outer radius of highlight
• offset - an offset applied to both r0 and r1 (useful for overriding default r0,r1 values defined at lower precedence)
• fill_color - color of the highlight slice
• stroke_color - color of the highlight border, drawn if stroke_thickness is set
• stroke_thickness - border thickness, if any, of the highlight slice
• z - z-depth of the highlight, controlling the order in which highlights are drawn ideogram - toggles the position of the highlight to be within the ideogram extent
