fasta-one-hot-encoder 1.2.1

Simple python to lazily one-hot encode fasta files using multiple processes.

Simple python to lazily one-hot encode fasta files using multiple processes, either single bases or considering arbitrary kmers.

Installation

Simply run:

pip installed fasta_one_hot_encoder

Examples

Bases

One-hot encode to bases.

from fasta_one_hot_encoder import FastaOneHotEncoder

encoder = FastaOneHotEncoder(
    nucleotides = "acgt",
    lower = True,
    sparse = False,
    handle_unknown="ignore"
)
path = "test_data/my_test_fasta.fa"
encoder.transform_to_df(path, verbose=True).to_csv(
    "my_result.csv"
)

Obtained results should look like:

	a	c	g	t
0	0	0	1	0
1	0	1	0	0
2	0	1	0	0

Kmers

One-hot encode to kmers of given length.

from fasta_one_hot_encoder import FastaOneHotEncoder

encoder = FastaOneHotEncoder(
    nucleotides = "acgt",
    kmers_length=2,
    lower = True,
    sparse = False,
    handle_unknown="ignore"
)
path = "test_data/my_test_fasta.fa"
encoder.transform_to_df(path, verbose=True).to_csv(
    "my_result.csv"
)

Obtained results should look like:

	aa	ac	ag	at	ca	cc	cg	ct	ga	gc	gg	gt	ta	tc	tg	tt
0	0	0	0	0	0	0	0	0	0	1	0	0	0	0	0	0
1	0	0	0	0	0	1	0	0	0	0	0	0	0	0	0	0
