# skbio.sequence.GrammaredSequence.mismatches¶

GrammaredSequence.mismatches(other)[source]

Find positions that do not match with another sequence.

State: Stable as of 0.4.0.

Parameters

other (str, Sequence, or 1D np.ndarray (np.uint8 or '|S1')) – Sequence to compare to.

Returns

Boolean vector where True at position i indicates a mismatch between the sequences at their positions i.

Return type

1D np.ndarray (bool)

Raises
• ValueError – If the sequences are not the same length.

• TypeError – If other is a Sequence object with a different type than this sequence.

Examples

>>> from skbio import Sequence
>>> s = Sequence('GGUC')
>>> t = Sequence('GAUU')
>>> s.mismatches(t)
array([False,  True, False,  True], dtype=bool)
