Issues of interfacing with protter chenb37  2015-10-15
 
Hi, when I used Protter tool before, it will direct me to the protter page and show the unique peptide selected in skyline in the protein structure.

But now it directs me to the home page of Wollscheid Group. I tried a few times of creating a brand new file, uninstalling and reinstalling protter and the problem remained the same. My operation system is windows 7 with IE 10, skyline version 2.6.0.6851

Could you take a look at this problem? Thank you very much!
