Hi Alejandro,
Without seeing the structure of your data table I can’t be very concrete, but in general the Gviz package should give you all the flexibility you need in order to create a DataTrack object from it. You may want to carefully (re-)read the section about DataTracks in the package vignette, and also the documentation for the DataTrack() constructor (by typing '? DataTrack’). Hopefully this will already get you much closer to a solution. If you still feel that you are stuck after doing this home work, please send me a reduced example of your conservation table (the first couple of rows suffice) and I can help you with more concrete code suggestions.
Florian

Subject: Question on Gviz

Hello Florian,
    I am so excited with the Gviz package. I like it a lot and I hope I can make some nice genomic graphics. I was wondering if you can help me to solve a little problem I have. Here is the thing, I am interested in plotting a track from tabular data via converting a phascons conservation table that I downloaded using galaxy as xxx.tabular which then I modified at the position column from mouse (mm9) to another species data using a MAFFT alignment.

I can plot the mm9 conservation table using UcscTrack but I cant plot the modified table I have in my folder because this is not in a datatrack format.

Is it possible to make the conversion?

I would appreciate any help and thanks in advance!

Cheers,
