__init__()

Overload:

__init__(self) → None

Overload:

__init__(self, in_0: OpenSwathHelper) → None

Methods

__init__	Overload:
checkSwathMapAndSelectTransitions(self, exp, ...)
computePrecursorId(self, ...)	Computes unique precursor identifier
estimateRTRange(self, exp)	Computes the min and max retention time value

checkSwathMapAndSelectTransitions(self, exp: MSExperiment, targeted_exp: TargetedExperiment, transition_exp_used: TargetedExperiment, min_upper_edge_dist: float) → bool

computePrecursorId(self, transition_group_id: bytes | str | String, isotope: int) → bytes | str | String

Computes unique precursor identifier

Uses transition_group_id and isotope number to compute a unique precursor id of the form “groupID_Precursor_ix” where x is the isotope number, e.g. the monoisotopic precursor would become “groupID_Precursor_i0”

Parameters:

• transition_group_id – Unique id of the transition group (peptide/compound)

• isotope – Precursor isotope number

Returns:

Unique precursor identifier

estimateRTRange(self, exp: LightTargetedExperiment) → List[float, float]

Computes the min and max retention time value

Estimate the retention time span of a targeted experiment by returning the min/max values in retention time as a pair

Returns:

A std pair that contains (min,max)
