Hi Martin, I've just tried to replicate the same procedure and when I select export peaks file for Sparky, the first dialog box contains a box with Sequence code start and a number in it. I have also, renumbered a residue 0 to be Met and if I put zero in this box, I get the correct numbering. However, if I try to export another peaks file, this box does not appear. This may indicate that once the choice is made, it persists. If I close analysis, re-open and try to export again, I get the same request to specify sequence code start. Hope this helps, Simon On Aug 27, 2013, at 10:40 AM, Martin Ballaschk wrote: > Hi all, > > I have a project which contains only one chain, and which I modified > to begin with residue number 0 (a Met) in the Molecule dialog. > Everything looks great while assigning and navigating inside > Analysis 2.2.2, but after exporting the peak list to a Sparky file, > all residues get remapped to 0 -> 1, 1 -> 2 and so on. > > See screen shot: > https://dl.dropboxusercontent.com/u/4019316/Screenshot-1.png > > I believe to remember that Analysis asked in the past where the > actual sequence starts (before I changed the first residue from > default 1 to 0), but I could not find the respective popup to change > it again. > > Does anyone know a solution? > > Best regards, > Martin
