How to access/run correlations on proteomics data

Issues and Bugs
1

Hi
I have been trying to correlate drug sensitivity with RPPA expression of ERBB2_py1248 across cell lines.
I used to do this by selecting custom analysis, then gene ERBB2, then I could select proteomics for ERBB2_py1248, which would give me volcano plots for whatever drug screen I selected, e.g. GDSC1.
Something seems to have changed in the last few weeks, I am not seeing the proteomics as a dataset option. I am not sure if it is moved or if I can still access it another way?
Thanks very much
