slow5-rs
A library for interacting with SLOW5/BLOW5 files in rust. Not official.
For more information checkout the main slow5lib repository.
Note: Library design is in flux and care should be taken in upgrading this crate.
Installation
Add the following to your Cargo.toml
:
[dependencies]
slow5 = "0.11"
Git
If you'd like to download the git version, use the following command to download the repo
git clone --recursive https://github.com/bsaintjo/slow5-rs.git
Getting started
Reading signal from SLOW5 file
use slow5::{FileReader, RecordExt};
fn main() -> Result<(), Box<dyn std::error::Error>> {
let mut slow5 = FileReader::open("examples/example.slow5").unwrap();
for record in slow5.records() {
for signal in record?.picoamps_signal_iter() {
// Do stuff
}
}
Ok(())
}
Writing a compressed BLOW5 file with attributes
use std::error::Error;
use slow5::{FileWriter, SignalCompression, Record};
fn main() -> Result<(), Box<dyn Error>> {
let tmp_dir = std::env::temp_dir();
let output = tmp_dir.join("test.blow5");
let mut writer = FileWriter::options()
.signal_compression(SignalCompression::StreamVByte)
.attr("attribute", "value", 0)
.create(output)?;
let rec = Record::builder()
.read_id("test_id")
.read_group(0)
.digitisation(4096.0)
.offset(4.0)
.range(12.0)
.sampling_rate(4000.0)
.raw_signal(&[0, 1, 2, 3])
.build()?;
writer.add_record(&rec)?;
writer.close();
Ok(())
}
