Method Details

[hide private]

init(self, parent=None, display_mode=<Format.one_letter: 1>, include_gaps=False)
(Constructor)

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:

parent (QtCore.Object) - Parent of the row based table model.
display_mode (ResidueFormat enum) - Display mode of the residues
include_gaps (bool) - Whether or not to include gaps in calculating alignment metrics, such as identity, similarity, etc.

Overrides: object.__init__

getResidueDisplayMode(self)

Returns: ResidueFormat: The residue display mode in current use

setResidueDisplayMode(self, mode)

Parameters:

mode (ResidueFormat) - The display mode for residue text

setAlignment(self, alignment)

Set the alignment model to display data from

Parameters:

alignment (schrodinger.application.msv.domain.alignment .BaseAlignment) - The alignment model

getAlignment(self)

Return the underlying alignment object

Returns: schrodinger.application.msv.domain.alignment.BaseAlignment: The alignment

sequenceCount(self)

Returns: int: The number of sequences in the alignment

notifyResidueSelection(self, selection)

Takes a list of residues and emits a list of indices corresponding to them.

We need this signal in order to convey selection changes from the structure model to the view.

Each proxy in the proxy stack should listen to the residuesSelected signal of its own model and then emit in turn its own residuesSelected signal with the indices appropriately modified

Parameters:

selection (list of schrodinger.application.domain.residue. Residue) - A list of residues to select
residuesSelected (list of QtGui.QIndex)

columnCount(self, parent=None)

Overrides: PyQt4.QtCore.QAbstractItemModel.columnCount

headerData(self, section, orientation, role=0)

Header data for the table. Untitled sequences will be given a title of "Sequence #".

See Qt documentation for argument and return value documentation

Overrides: PyQt4.QtCore.QAbstractItemModel.headerData

_calculateValueRange(self, values)

Calculate the difference between the maximum and minimum values in a list

Parameters:

values (list) - The value to calculate the range of

Returns: float

The difference between the max and min values
