Search with deuterium modifications

Postby curly » Thu Sep 15, 2016 2:44 am

Hello,

We have samples in 'heavy water' rather than water. When carrying out a search in mascot/xtandem etc, is there a method to add a variable modification that would cater for hydrogens being replaced by deuteriums. ie adding +1 to the masses of all the hydrogens in the peptides.

Many thanks.
