BiocFrame

BiocFrame provides a base Dataframe class, intended to be a flexible data structure compared to Pandas DataFrame This would be interoperable with pandas but will support usecases in genomics.

Install

Package is published to PyPI

pip install biocframe

Usage

Lets create a DataFrame from a dictionary

from biocframe import DataFrame

df = DataFrame(
    data = {
        "seqnames": [
            "chr1",
            "chr2",
            "chr2",
            "chr2",
            "chr1",
            "chr1",
            "chr3",
            "chr3",
            "chr3",
            "chr3",
        ]
        * 20,
        "starts": range(100, 300),
        "ends": range(110, 310),
        "strand": ["-", "+", "+", "*", "*", "+", "+", "+", "-", "-"] * 20,
        "score": range(0, 200),
        "GC": [random() for _ in range(10)] * 20,
    }
)

Access Properties

A couple of accessor methods/properties are available to access column names and dims

# find the dimensions
print(df.dims)

# get the column names
print(df.colnames)

Setters

Using the Pythonic way to set values

# set new column names
df.colnames = [... new colnames ...]
print(df.colnames)

# add or reassign columns

df["score"] = range(200, 400)

Slice the `DataFrame`

Currently slicing is only supported by indices. A future version may implement pandas query like operations.

sliced_df = df[3:7, 2:5]
