[CV] Request new entry: base peak intensity maximum

[julianu]

What is the QC term's name?

base peak intensity maximum

Briefly describe the QC term.

this metric should capture the maximum value of a run's base peaks

What is the QC term's unit?

intensity / arbitrary

Value type

MS:4000003 ! single value

Describe any additional information.

• this term is ID-free and can easily be calculated using all spectra (MS1 and MS2)
• it is applicable to a single run
• the value should be (relatively) constant for same / similar samples

[bittremieux]

There currently is MS:1000505 ! base peak intensity, so we should at least add a related relationship to that.

The difference here is that this would be the maximum base peak intensity across all spectra? Are MS1 and MS2 spectra comparable on this metric?

[julianu]

In my understanding, there is no real consensus whether the base peak is calculated only by MS1/MS2 or by both. The maximum though is almost always originating from a MS1 (at least in the data we analysed).

So, yes, it would be the maximum of the MS:1000505 ! base peak intensity of all spectra.
