Spectral similarity¶
- dotProd(ms2A, ms2B, mzTol=0.02)¶
Calculate the MS2 spectral similarity by dot product.
- Parameters:
ms2A – a
ms2Spectrum
object. The first MS2.ms2B – a
ms2Spectrum
object. The second MS2.mzTol – float. Tolerance of the m/z difference in Da. Default is 0.02.
- Returns:
float. The dot product similarity score between the two MS2 spectra. Returns 2.0 if either MS2 does not exist.
To use this function:
dp = dotProd(ms2A, ms2B)
print(dp)
