It is weird that no peaks picked. Can you send me a screen shot of pv window? I would suggest a few things:

1. Play with tolerances.

2. Check peak intensities if inverted.

3. Check properties of spectra by using ucsfdata if spectral resolutions and widths and carrier positions cannot be used to determine dimensions.

4. Use restricted peak picking (two-letter-code kr)

You can also share the data to me privately as well (whlee At nmrfam.wisc.edu).

Best,
