Dear Vasantha,

I can think two methods for now.

First, probably is not using peak centering or not dragging a box to pick a peak but only clicking on it in the fairly zoomed in screen.

Second, you can save peak list file, edit in text editor, read it by rp.

There may many other workarounds.

Best,

Woonghee

Dear All

I have a quick question on the automatic alignment of the assigned side chain peaks belongs to the same HN peak.Automatic peak picking or peak centering on the side chains (F1) changes the peak position if spectra are not well resolved. Because of that sparky generates deviation if peaks of HA HN HG HD are not perfectly aligned to same HN frequency.

In cara/neasy there is a option if I select all side chain peaks give command move reference it aligns all the side chain peaks to same HNs..

So I am searching for the same command in SPARKY. I have to deal with natural abundance peptide only 2D tcosy/noesy spectra. Your suggestions would be a great help...

thanks
