Usage

cramino [OPTIONS] <INPUT>

ARGS:
    <INPUT>    cram or bam file to check

OPTIONS:
    -t, --threads <THREADS>    Number of parallel decompression threads to use [default: 4]
        --hist                 If histograms have to be generated
        --checksum             If a checksum has to be calculated
    -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
• calculating a normalised number of reads per chromosome, e.g. to determine the sex or aneuploidies (--karyotype)
• histograms of read lengths and read identities, as below. (--hist)
