HcccoNH cannot restrict pick the signals

Analysis Version 3
#1

Hello,

I am restricting picks in an HcccoNH to assign protons and they are not picked. I make sure i am in the maximum. If I play with the tolerances and increase them what i get is an unspecific peak picking. Why is this happening? How can i pick the peaks correctly?

Thank you.

Hi Alex,

the restricted picking doesn’t work very well for HHN spectra in V3.0.4 - hoping to get this sorted properly for 3.1.
A hack in the meantime: Set your H1 tolerance to something like 20 (about twice the sweep width of your spectrum in ppm). Then it should work.
