pinned X-CNV executable. Chromosome names may use the executable's leading
chr convention, and coordinates are retained as integer values.
Usage
validate_cnv(x)
Arguments
x
A path, data frame, or matrix containing chromosome, start, end,
and CNV type in its first four columns.
Value
TRUE invisibly when validation succeeds; otherwise an ordinary R
error is raised.
