get_subsequences_all_sequences()

Counts the number of distinct subsequences for each sequence.

Function Usage

from sequenzo import get_subsequences_all_sequences, get_subsequences_in_single_sequence
result = get_subsequences_all_sequences(seqdata, dss=True, with_missing=False)

For one already encoded sequence row, get_subsequences_in_single_sequence() is the lower-level helper used by the all-sequences function.

Entry Parameters

• seqdata: SequenceData object.
• dss: remove consecutive duplicates before counting.
• with_missing: include missing states during counting.

Returns

DataFrame with subsequence counts per sequence.
