CRAMINO

A tool for quick quality assessment of cram and bam files, intended for long read sequencing.

Installation

Preferably, for most users, download a ready-to-use binary for your system to add directory on your $PATH from the releases.
You may have to change the file permissions to execute it with chmod +x cramino

Alternatively, use conda to install
conda install -c bioconda cramino

Or for Rust developers, build cramino with cargo:
cargo install cramino

Usage

cramino [OPTIONS] <INPUT>

ARGS:
    <INPUT>    cram or bam file to check (or - to read from stdin)

OPTIONS:
    -t, --threads <THREADS>            Number of parallel decompression threads to use [default: 4]
    -m, --min-read-len <MIN_READ_LEN>  Minimal length of read to be considered [default: 0]
    --hist                             If histograms have to be generated
    --checksum                         If a checksum has to be calculated
    --arrow <ARROW>                    Write data to a feather format
    --karyotype                        Provide normalized number of reads per chromosome
    --phased                           Calculate metrics for phased reads
    --spliced                          Calculate metrics for spliced reads
    -h, --help                         Print help information
    -V, --version                      Print version information

Example output

File name       example.cram
Number of reads 14108020
Yield [Gb]      139.91
N50     17447
Median length   6743.00
Mean length     9917
Median identity 94.27
Mean identity   92.53
Path    alignment/example.cram
Creation time   09/09/2022 10:53:36

A 140Gbase bam file is processed in 12 minutes, using <1Gbyte of memory. Note that the identity score above is defined as the gap-compressed identity.

Optional output

a checksum to check if files were updated/changed or corrupted. (--checksum)
an arrow file for use within NanoPlot and NanoComp (--arrow <filename>)
calculating a normalised number of reads per chromosome, e.g. to determine the sex or aneuploidies (--karyotype)
information about the phase blocks. (--phased)
histograms of read lengths and read identities, as below. (--hist)
