Container to represent data from genomic experiments
Project description
SummarizedExperiment
Container to represent data from genomic experiments, follows Bioconductor's SummarizedExperiment. It uses efficient structures already available in the Pandas/numpy eco-system & adds a familiar interface.
Install
Package is deployed to PyPI
pip install summarizedexperiment
Usage
Currently supports both SummarizedExperiment
& RangeSummarizedExperiment
objects
First create necessary sample data
nrows = 200
ncols = 6
counts = np.random.rand(nrows, ncols)
df_gr = pd.DataFrame(
{
"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,
}
)
gr = GenomicRanges.fromPandas(df_gr)
colData = pd.DataFrame(
{
"treatment": ["ChIP", "Input"] * 3,
}
)
To create a SummarizedExperiment
,
tse = SummarizedExperiment(
assays={"counts": counts}, rowData=df_gr, colData=colData
)
To create a RangeSummarizedExperiment
trse = SummarizedExperiment(
assays={"counts": counts}, rowRanges=gr, colData=colData
)
