ValidateName #

Verify that all segments have the same read name (or a shared prefix).

[[step]]
    action = "ValidateName"
    # Optional separator character; the comparison stops at the first match
    readname_end_char = "_" # Optional. Do not set for exact matching. Otherwise, a byte character
    sample_stride = 1000 # Check every nth fragment, default 1000. Must be > 0. Starts with first read

When no separator character (readname_end_char) is provided the entire name must match exactly across all segments.

When a readname_end_char is provided, it must occur in the read names.

The read names are truncated after the first readname_end_char, and the prefixes must match exactly.

For example, use readname_end_char = "_" for typical older Illumina _1/_2 suffixes.

Note that this validation requires at least two input segments so there is a name to compare against, fastqrab will return an error otherwise.

See also: ValidateReadPairing which confirms read names are within a hamming distance of each other.
