Hi everyone, I'm making a nice circo plot for my research and I'm having a trouble trying to plot axes for several stacked data tracks, so I need to place the axes on front with the Z = 10 coordinate. In the documentation for Axes and background http://circos.ca/documentation/tutorials/quick_start/axes_and_backgrounds/lesson, is pointed out an option to draw axes inside a bare plot block <plot> not indicating a specific type of plot, just a bare plot block. The problem is when I run the .conf file, the prompt says that I need to specify the type of plot to be draw... weird thing since the documentation says the opposite...
This is my code:
<plot>
r0 = 0.83r
r1 = 0.98r
z = 10
<axes>
<axis>
position = 0.5r
color = grey
thickness = 2
</axis>
<axis>
position = 0.166666r
color = grey
thickness = 2
</axis>
<axis>
position = 0.833333r
color = grey
thickness = 2
</axis>
</axes>
<backgrounds>
<background>
color = vvlgrey
</background>
</backgrounds>
</plot>
The error is:
*** CIRCOS ERROR ***
You must specify a type for a track. Choose one of
[scatter,line,histogram,heatmap,highlight,tile,text,connector].
Hope you can help me, if you need more information just ask and I'll be glad to provide it
Hi, could you state the biological relevance of your visualization?
Yes!, the track I want to display is about SNV densities in 100kb windows across the genome. In the axes block (not able to plot yet) I want to show lines for standard deviations, the axis plotted in the position 0.5r is showing SD = 0, so the window are near to the mean number of variants; the line plotted at 0.16666r shows SD = -2 so lower densities, and line at 0.8333r shows SD = 2 so genomic windows very rich in variants. All this will help to pinpoint interesting high-low genomic regions for further examination (genes affected with those variants, etc).
