◆ deconvoluteChargedState()

bool pappso::MassSpecTracePlotWidget::deconvoluteChargedState ( int span = 1)

Deconvolute the mass peaks into charge and molecular mass.

This is one of two methods to deconvolute mass data into a charge value and a Mr value. The method implemented in this function is based on the charge state envelope offered by the mass spectrum (most often for polymers of a reasonable size).

Parameters
spanvalue representing the number of peaks of the charge state envelope that are spanned by the user selection. Defaults to 1, that is, the span encompasses two consecutive mass peaks of a given charge state envelope.

Set m_lastMz, m_lastZ and m_lastMass.

Returns
true if the deconvolution could be performed, false otherwise.

◆ deconvoluteIsotopicCluster()

bool pappso::MassSpecTracePlotWidget::deconvoluteIsotopicCluster ( )

Deconvolute the mass peaks into charge and molecular mass.

This is one of two methods to deconvolute mass data into a charge value and a Mr value. The method implemented in this function is based on the distance that separates two immediately consecutive peaks of an isotopic cluster. This method can be used as long as the instrument produced data with a resolution sufficient to separate reasonably well the different peaks of an isotopic cluster.

Set m_lastMz, m_lastZ and m_lastMass.

Returns
true if the deconvolution could be performed, false otherwise.

◆ mouseMoveHandler()

void pappso::MassSpecTracePlotWidget::mouseMoveHandler ( QMouseEvent * event)
overridevirtual

Handle mouse movements, in particular record all the last visited points.

This function is reponsible for storing at each time the last visited point in the graph. Here, point is intended as any x/y coordinate in the plot widget viewport, not a graph point.

The stored values are then the basis for a large set of calculations throughout all the plot widget.

Parameters
pointerto QMouseEvent from which to retrieve the coordinates of the visited viewport points.
