The standard CNV segment file is a tab-delimited list, including the sample UID in the first column:
sampleID chro basestart basestop segvalue probes GIST-ass-15 1 0 124299999 -1 NA GIST-ass-16 1 142400000 149599999 1 NA ...
Depending on the active page, the value may be the original log2 value from an array or the status marker. “Probes” will only display a value when plotting array specific data.
|Please be aware that segments may be filtered out if values below the standard threshold (0.15||-0.15) are provided, or very small numbers are given for probes (leaving them empty is o.k.).|
