Peak Volume display range

Author mukherji

I have been using cara for more than 10 years. But recently I am facing a problem with maximum peak volume display. The peaks are showing up as contours with huge vacuole in the middle. I have tried all possible settings in the contour parameters menu but to no avail. I have come to the conclusion that my peak intensity is too high (> 5e8) and this could be the reason for such peak display.
How do I overcome this problem?

This problem may arise because of the change in intensity scale for recent topspin versions.
I assume it wasn't possible to fix the issue by using very large contour threshholds like 1e9.
Did you try to either reduce the intensity scale in the program used for processing the spectra?

I'm currently facing the same problem. No idea how to solve it. But when I set to auto contour level I can see peaks fine. But disabling the auto contour again brings the problem back. Does anyone have a solution?
