RuntimeWarning: Mean of empty slice #9

Closed heejongkim closed 6 years ago

Hi,

As I'm doing the combined postMascot process, one line of warning was caught by my eyes.

C:\py279_32\lib\site-packages\numpy\core_methods.py:55: RuntimeWarning: Mean of empty slice. warnings.warn("Mean of empty slice.", RuntimeWarning)

I'm not sure if I need to be concerned about this warning or not but, generally, if I ignore it, it comes back to me as a huge problem so I'd like acknowledge it so that I can move on.

Can you please help me understand where (at which stage) it gets produced and why?

Thank you!

best, hee jong kim

hi hee jong kim, That warning is thrown by numpy (as you can see from the warning itself) it occurs during the protein quantification stage and likely applies to a protein that has one missing label;. You do not need to worry about it - your data will be just fine best Toby
