how to get the nominal mass data

[skywalker-andy]

I just extract the exact mass data through the Thermo Xcalibur Qual Brower. At the same time, i could get the exact mass data through pymsfilereader,which is the same as i extract from the Thermo Xcalibur Qual Brower. (Thanks. It,Pymsfilereader.py, helps me a lot. ) But in the Thermo Xcalibur Qual Brower, i can get the nominal mass,which i currently can not find the function in the pymsfilereader.py. I want to ask that the pymsfilereader.py whether support this function if i use it.
