step producing file _battenberg_cn.vcf.gz

from battenberg.

I thinks this is caveman/ASCAT output and not generated by the current battenberg pipe.
I believe the "subclones.txt" file has the same data ie segment CN data.

Dear Sames,

Thanks so much for the clarification.

That file you mention "subclones.txt", which is indeed produced, does it contain the actual CN values as they are displayed in the segmentation plots?

Many thanks
Jorge

Im going to say yes. To be honest Im not entirely sure what the exact realationship between the subclones file and the copy number profiles is. I can't reconcile them, completely. It would be great to have some input from a Battenberg pro!

battenberg.pl is part of cgpBattenberg and handles conversion into more widely standardised bioinformatic files.

• battenberg_CN_to_VCF.pl converts the subclones file to a VCF file
• bb_vcf_to_ascat_cn.pl reads the major CN and generates a simple segment bed file

The subclones.txt file contains the copy number calls. The subclones_1.txt file is produced before the subclones.txt file, the difference between the two being that adjacent segments with the same copy number are merged. The subclones.txt file contains exactly the same subclones as those shown in the subclones.png (and summarised genomewide in the _subclones.png and _average.png files), in the '*_A' columns.
