Re: [Breakdancer-help] issue with BreakdancerMAX and MINI

[Swetansu P. <swe...@gm...>]

Hey Ken,
The bam2cfg.pl was run successfully to create the cfg file.
However,  we are encountering certain discrepancies in the number of
predicted Structural Variations when we run  the whole genome versus
when we run it chromosomewise using the -o option of
BreakDancerMax.pl. More specifically, the -o option which yields
intrachromosomal variations and the -t option which works exclusively
of -o to predict the whole genome translocations does not add up to
the number of variations predicted by the program for whole genome
(perl BreakdancerMax.pl -l configfile.cfg).
Please let me know if you need extra info.
Thanks
Swetansu
PS: Our data is Illumina long insert (mate-pair) library.
