I'm analyzing TCGA Copy number alteration data using the GAIA package in R.
After runGAIA, I knew that there was an issue.
In general, the start position of a chromosome has to be smaller than the end position.
However, several start position numbers are larger than the end position, which means the value of the end position - start position + 1 becomes negative.
What is this means? And how can I solve this issue?
Thank you for your comments.
