Hi,
I copied peaks from one NH-HSQC to another and the set copied to a new
spectrum is offset by 2.95 ppm. Any idea what has gon wrong ?
There was no traceback.
The set I was copying is a part of the crosspeak set imported from Ansig.
The two spectra have slightly different sweep-widths, giving a few folded
peaks. Prior to copying the peaks I adjusted the referencing in both
spectra by going "Edit Spectrum/Referencing" - change the values for
"Reference ppm".
I think i didn't get the Minimum/Maximum aliased frequencies quite right,
because I am getting some "tiling" passed the edge of the spectrum.
There is a hint that something is not right with the crosspeaks
setup in the first place is that assignments don't appear to have fully
"stuck" after the linkResonances, that is with "Crosspeaks/Draw
Parameters" set to "Mininmal Annotation" I see the residue name and
number (the correct ones), but in "Peak List Editor" tables only amino
acid type seems to be assigned, all of the entries are in form:
{12}Leu{18}{12}Leu{17}; same appearance in spectrum window, when "Mininmal
Annotation" is off.
Problem with updating the tables from the resonaces data base ?
