6.3.2.5. starch-diff

This tool allows the end user to quickly compare the compressed chromosomes in two or more v2.2+ Starch archives.

6.3.2.5.1. Inputs and outputs

6.3.2.5.1.1. Input

The starch-diff utility takes in two or more Starch v2.2+ archives as input. The end user may also add –chr <chr> to compare one chromosome directly; otherwise, all chromosomes in specified archives are compared.

6.3.2.5.1.2. Output

The typical output of starch-diff is a message indicating the archives’ chromosome(s) are identical or dissimilar.

In addition, if the chromosomes are identical, starch-diff exits with a zero status code. Likewise, if any chromosomes are dissimilar, starch-diff exits with a non-zero status code.

6.3.2.5.2. Requirements

If the user passes in a pre-v2.2 archive, the utility will exit with a fatal error.
