Dear All,

I am trying to analyze some TCGA CNV data using the GAIA package. I followed the tutorial from @kevinblighe. Everything runs well and at the end, the error below come up. Has someone witnessed this before anc could some one propose a solution.

I previously ran this code about a year ago and it worked well.

Thank you
