Method Details

[hide private]

init(self, elements, name=`''`, alphabet=residue.AMINO_ACIDS_ONE_AND_THREE_LETTER, origin=None, entry_id=`''`, chain=`''`, unknown_res_type=residue.UNKNOWN, gap_chars=`['~',` `'-',` `'.']`)
(Constructor)

Make a sequence object from a list of strings, using a mapping of strings to element types.

Parameters:

elements (list) - An iterable of string representations of elements making up the sequence
name (basestring) - The name of the sequence
alphabet (dict) - A mapping of string representations of elements to element types
unknown_res_type (object) - The type, if any, of an unknown residue
gap_chars (set of basestring) - A set of permissible gap characters in the element list, the first of which will be used in serialization

Raises:

ValueError - If the unknown_res_type is None and an unrecognized character is encountered in the element list

Overrides: object.__init__

_makeSeqElements(self, elements)

Return a list of elements converted to proper sequence items

Parameters:

elements (list) - list of basestring or basestring

Returns: list

list of residues

Raises:

ValueError - If an element is not in self.alphabet and self._unknown_res_type is not defined

Overrides: Sequence._makeSeqElements

makeSeqElement(self, element)

Parameters:

element (basestring or schrodinger.application.msv.domain .residue.Residue) - A sequence element or string representation thereof

Returns: schrodinger.application.msv.domain.residue.Residue

residue

insert(self, index, elements)

Insert a list of elements or sequence element into this sequence

Parameters:

index - The index at which to insert elements
elements - A list of elements to insert

Overrides: Sequence.insert

(inherited documentation)

mutate(self, start, end, elements)

Mutate sequence elements starting at the given index to the provided elements

Parameters:

start - The index at which to start mutating
end - The index of the last mutated element
elements - The elements to which to mutate the sequence

Overrides: Sequence.mutate

(inherited documentation)

append(self, element)

Appends an element to the sequence

Parameters:

element - The element to append to this sequence

Overrides: Sequence.append

(inherited documentation)

extend(self, elements)

Extends the sequence with elements from a list

Parameters:

elements - The list containing elements with which to extend this one

Overrides: Sequence.extend

(inherited documentation)

sanitize(self, start=0, end=None)

Remove gaps and unknown sequence elements from sequence

Overrides: Sequence.sanitize

getGapCount(self)

Returns:: the number of gaps in the sequence

isValid(cls, elements, alphabet=residue.AMINO_ACIDS_ONE_LETTER, gap_chars=`['~',` `'-',` `'.']`)
Class Method

Parameters:

elements (list) - An iterable of string representations of elements making up the sequence
alphabet (dict) - A mapping of string representations of elements to element types
gap_chars (set of basestring) - A set of permissible gap characters in the element list

Returns: Tuple of (bool, set)

Tuple indicating whether valid and a set of invalid characters, if any

Overrides: Sequence.isValid
