No peak detected #4

Hi @tkimhofer,

When I was playing msbrower with my own data, and I got the following error:

No peaks detected- change parameter values!
Performing peak picking (centWave)
Detecting mass traces at 25 ppm ... OK
Detecting chromatographic peaks in 299 regions of interest ...Warning in .centWave_orig(mz = mz, int = int, scantime =     scantime, valsPerSpect = valsPerSpect,  :
No peaks found!
FAIL: none found!
done!

So I used your example data with the same centwave parameters following your video tutorial, but the same error appeared.

I don't know what the problem could be. Could you please help?

Thanks,

Dong
