Hi,
I am testing ExomeCopy on a set of illumina sequencing data generated
after agilent custum gene set capture, only 35 gene exons overall (~
300 Mb total).
1-My first question would be : is the method reliable for smaller
capture?
2-Secondly.,
I sucessfully used the method on the data provided with the vignette.
I then tried with my own set of data
in total 10 samples, across 2282 rows , I have calculated the GC and
bg values nad went on to the next step where I ran exomeCopy on one
sample and one chromosome
###this seems to work for certains samples, expect the warning for
small subset
> fit <- exomeCopy(rdata["Chr10"], sample.name = exome.samples[10],
+ X.names = c("bg", "GC", "GC.sq", "width"), S = 0:6,
+ d = 2)
Warning message:
In exomeCopy(rdata["Chr10"], sample.name = exome.samples[10], X.names
= c("bg", :
exomeCopy was tested for thousands of ranges covering a targeted
region on a single chromosome. The results might not be reliable for
less than a hundred ranges.
###then I try with another sample and got this error message
Error in if (goto.cnv < 1/(nstates - 1)) { :
missing value where TRUE/FALSE needed
I am not sure where this comes from and would like some help on this
> fit <- exomeCopy(rdata["Chr10"], sample.name = exome.samples[7],
+ X.names = c("bg", "GC", "GC.sq", "width"), S = 0:6,
+ d = 2)
Error in if (goto.cnv < 1/(nstates - 1)) { :
missing value where TRUE/FALSE needed
In addition: Warning message:
In exomeCopy(rdata["Chr10"], sample.name = exome.samples[7], X.names =
c("bg", :
exomeCopy was tested for thousands of ranges covering a targeted
region on a single chromosome. The results might not be reliable for
less than a hundred ranges.
