get_turbulence()

Computes turbulence for each sequence from subsequence diversity and spell-duration variance.

Function

from sequenzo import get_turbulence
result = get_turbulence(seqdata, norm=False, silent=True, type=1, id_as_column=True)

Parameters

• seqdata: SequenceData object.
• norm: normalize turbulence value.
• silent: suppress progress messages.
• type: spell-variance type (1 or 2).
• id_as_column: return ID as a regular column.

Returns

DataFrame with turbulence values by sequence.
