I am trying to understand the resolution setting on 'isotopicdist.m' function. In the HELP page regarding the resolution value, it shows:
Value in daltons specifying the approximate resolution of the instrument, given as the Gaussian width at full width half height (FWHH).
Default: 1/16 Da"
However inside the function itself, at line 543 it described:
"w = 1/8; % Width of the Gaussian pulse (in Daltons), usually this value should match the resolution of the instrument."
Are they talking about the same thing? If I want to edit the resolution, is value w the one I should change? What's the differencies between this instrument resolution w and resolution calculated based on R=M/FWHH, where M is m/z.
