Hello Tom,
the full region is needed to compare (overlay) with COSY/TOCSY specs and as well to see the patterns of connectivities.
All I said before was without labels and peak assignments!!
As I said, now Im getting used to display several small fractions of the full spectra ....

By your question I gess that you want people to add the name.ps ...I did that
and it says Cant open file s54. for printing....and reports printing failed....although now it prints/saves a ps file which I can open in Corel with good quality.

Ill try in Linux later.

Question: Its possible to calibrate a 2 D spec. in Sparky?

Thanks again
best regards: PP

Hi,

Looking at 2900 peaks when the full spectrum is displayed cant
allow you to distinguish anything. Is the reason you look at the full
spectrum in order to navigate to the region you want? -- zoom all the
way out, then zoom in to the small region of interest?

On my 4 year old laptop running Linux (Redhat Enterprise 4) it takes
less than 1 second to draw contours of a 512 by 1024 regions of a 2-d
spectrum the second time. This is with 16 contour levels, contoured
above the noise level. Maybe the slowness you observe is because the
drawing of 2900 peak markers and assignment labels is slow. As a test
you could hide all labels using pa (select all peaks) and lB (hide labels).
You could also for testing purposes delete all peaks (dont save!).
I tried using contour levels deep in the noise and still it takes 2 or 3
seconds to redraw a 512 by 1024 region on this old machine.

When you get Cant open file s2lc. for printing, what file name are
you providing for saving the file?
