FindPeaks with Decimate done before

[ThScEo]

Hello,

First of all, thank you for this useful package!

• I encounter issue when trying to find peaks on decimated samples.

• I can easily find peaks without using decimate() (from spectrum or chromatogram), but when I use decimate() function before, even if the shape of the curve seems to be identical to the non-decimated sample ( I checked that decimation did not modified the curve shape too strongly), findPeaks function find nothing, or at least less peaks than on the non-decimated sample.

• I tried several factor for RT and DT axis, even with a factor = 2 for both axis, less peaks are found.

• Could you explain me why? Maybe I am missing something!

• Here is an example:

  • find Peaks on decimated sample with a factor 2 for both axis:

  • find Peaks on non-decimated sample :

Thank you

Hi,

Apologies for having trouble with the peak detection.

I will do my best to reproduce the error and get it fixed.

Could you please send me (or attach here) a small reproducible example just to make sure I can reproduce your issue (ideally including one sample)?.

Thanks!
