using ABSOLUTE for sequencing data

Hello,

Can you explain how to use ABSOLUTE for cancer DNA sequencing data? I
searched for

http://www.broadinstitute.org/cancer/cga/absolute_run

But did not find enough information. Specifically, ABSOLUTE requires the
input data to have at least four columns:
"Chromosome", "Start", "End", "Num_Probes" and "Segment_Mean"

For my sequencing data, I have done the segmentation already, and I have
"Chromosome", "Start", "End", plus the number of reads mapped to the
segment in tumor sample "d_T", and the number of reads mapped to the
segment in matched normal sample "d_N". So, I'm wondering how to convert
these "d_N", "d_T" into "Num_Probes" and "Segment_Mean" for ABSOLUTE?

Thanks so much!

I was wondering the same

I was wondering the same thing myself.

I was using bins segmented with DNACopy (R).

num_probes == num bins in a segement

I was wondering what was the recomendation of how to transform WGS into the ABSOLUTE format.
