[CV request] spike in sample metrics

[julianu]

What is the QC term's name?

spike in sample table

Briefly describe the QC term.

This table should hold several information about spike in measurements. It is basically an extension of the "QC2 sample intensities" (MS:4000079), but allowing any peptides, not only the ones in the QC2 sample.

The first column should be the spike in peptide, followed by metrics. For us, these are right now:

• MS:1001843 ! MS1 feature maximum intensity
• retention time (of this maximum intensity)
• delta to expected retention time
• number of identifications / PSMs

What is the QC term's unit?

No response

Value type

MS:4000005 ! table

mzQC call: include column for mass accuracy as well.

CV terms for the columns would thus be:

• MS:1001843 ! MS1 feature maximum intensity
• MS:4000072 ! observed mass accuracy
• MS:1000894 ! retention time
• Either MS:1000897 ! predicted retention time from which the delta retention time can then be calculated, or a new term for the latter directly.
• MS:1003251 ! count of identified spectra
